The area of a rectangle is given by
lw = A
11.8x = 47.6
Divide each side by 11.8
11.8x/11.8 = 47.6/11.8
x =4.033898305
To the nearest tenth
x = 4.0
Answer:
algebraic equation; 11.8x = 47.6
width = 4.0
Step-by-step explanation:
solve the algebraic equation to get x, the width.
11.8x = 47.6

Factor the Trinomial
x^2+12x+27
Answers
Answer:
(x + 9)(x + 3)
Step-by-step explanation:
Factor 27 so that the factors, when combined, will equal 12:
x² + 12x + 27
x 9
x 3
(x + 9)(x + 3) is your answer.
Check: Use the FOIL method. Multiply the first two terms, the outside terms, the inside terms, and then the last two terms. Combine like terms:
(x + 9)(x + 3) = x² + 3x + 9x + 27 = x² + 12x + 27 (√)
~
Answer:
(x+9)(x+3)
Step-by-step explanation:
first of all, you should learn this properly, because you'll have to go back to this over and over again. anyways
you need to find two numbers so that it adds up to 12, but also multiplies to 27.
The numbers 9 and 3 fit the situation
So you add 9x and 3x because it's the same thing as 12x. you're just splitting up the term 12x into two other terms.
so now it looks like x^2 + 9x + 3x + 27. now you factor the first two terms and last two terms
x ( x + 9 ) <---factor of first two terms
3 ( x + 9) <---factor of last two terms
x(x+9)+3(x+9)
you notice that (x+9) is common in both factorized parts
so, you add x and 3 from the outside
and you get (x +3 ) (x+9)

How would I solve this?
4a-6=-2+14
Answers
Solving these equations can prove to be tricky, but once you understand them, ridiculously easy! Remember: your goal is to reduce it to (variable=number). Make sure to use opposite operations to cancel out numbers, and don't forget what you do to one side you must do to the next. There isn't one true order, but you'll know you have a great understanding of what you're doing if you can solve it numerous different times and wind up with the same result!
Set up the equation!
[tex]4a-6=-2+14[/tex]
Let's try subtracting 14 from both sides! We must do the opposite operation to cancel it out.
[tex]14-14=0\\-6-14= -20[/tex]
Now we have
[tex]4a-20=-2[/tex]
We have to start on the left side now, because we can't have an equation with one blank side. The number you start with will end up getting canceled out, as 0. How about we add 20 to both sides?
[tex]-20+20=0\\-2+20=18[/tex]
Now we have
[tex]4a=18[/tex]
Next, we have to apply the opposite opperation to both sides. The only opperation left is multiplication (4a). Therefore, we need to divide by 4, because we have to isolate a.
[tex]4a/4=a\\18/4=4.5[/tex]
Now we have
[tex]a=4.5[/tex]
Your answer is a=4.5!
Remember: Combine like terms first, it's much easier!

Greg plans to purchase a bicycle. Bike A costs $270 and has an expected maintenance cost of $36 per year. Bike B costs $360 and has an expected maintenance cost of $20 per year. Which statement is true based on the average annual cost of each bike?
Answers
Answer:
Bike A costs $270 and has an expected maintenance cost of $36 per year."Bike A is the better choice if Greg plans on owning the bike for 5 years. Bike B is the better choice if Greg plans on owning the bike for 6 years."Step-by-step explanation:
270-36x
there are 5 years so x=5
270 + 36(5) = 270 + 180 = 450
If it were 6 years than x = 6
270 + 36(6) = 270 + 216 = 486
Bike B:
360 + 20x
For option b x = 5
360 + 20(5) = 360 + 100 = 460
for option b it would be 6 years than x = 6
360 + 20(6) = 360 + 120 = 480

The parks department is installing a
fence along a scenic overlook. The area
to be lenced has 3 sides measuring 4V5
feet. 3 v 5 leet, and 5V5 feet. Find the
total amount of fencing that needs to be
installed.
Answers
Answer:
60 square feet.
Step-by-step explanation:
The area to be fenced has two rectangles and one square. We add the areas of the rectangles to that of the square to obtain the total amount of fencing required.
Area of 4 × 5 feet rectangle =(4 × 5) = 20 square feet
Area of 3 × 5 feet rectangle =(3 × 5) = 15 square feet
Area of 5 × 5 feet square =(5)² = 25 square feet
So the total amount of fencing that need to be installed is 20 + 15 + 25 square feet = 60 square feet.

8. Shelley and Jim sold tickets to the basketball game. Good seats were $3 each and not so good seats cost
only $2 each. 150 people attended the game and Shelley and Jim collected $350. Write the system. How
many of each type of seat did they sell?
Answers
Answer:
100 not so good seats
50 good seats
Step-by-step explanation:
Let x represent good seats and y represent not so good seats
[i] 3x + 2y = 350
[ii] x+y = 150
[iii] y = 150 - x
substitute this to equation [i]
3x + 2y = .350
3x + 2 (150-x ) = 350
3x + 300 - 2x = 350
3x-2x = 350 - 300
x = 50 good seats
now substitute what you got to equation [iii]
y = 150 - 50 = 100 not so good seats
when we check the answer by using equation [i] we find that it is correct:
3x + 2y = 350
3(50) + 2(100) = 350
150 + 200 = 350
350 = 350
Find the area of a circle with a diameter of 56 millimeters.
Answers
Answer: 784π mm²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle which is shown below.
Area = πr²
Notice that here, we're given the diameter instead of the radius.
Remember that the radius is equal to half of the diameter. So the radius of this circle will be equal to half 56 millimeters or 28 millimeters.
So plugging into the formula, we have (π)(28 mm)².
A common mistake is to plug 56 millimeters into the formula but remember that we must plug in the radius and not the diameter.
Multiplying, (28 mm)² is equal to (28 mm)(28 mm) or 784 mm².
So we have 784π mm².
So the area of the circle is 784π mm².
Denise and Jacqueline are training for a swimming and running race.
• Jacqueline swims for 30 minutes. Then she runs 3.2 miles at a constant
pace. Her total training time is 54 minutes. • Denise swims for 24 minutes.
She runs at a constant pace of 8 minutes per mile. Her goal is to train for at
least 60 minutes. *
Part A: Write an equation or inequality to represent the pace, in minutes per mile, that Jacqueline
runs. Define all variables used. At what pace, in minutes per mile, does Jacqueline run? Show your
work. Respond in the space provided.
Answers
Answer:
Jacqueline runs at 6.25 minutes per mile
Step-by-step explanation:
Here we have that the total training time for Jacqueline = 54 minutes
The time for which Jacqueline swims = 30 minutes
Therefore, the time in which Jacqueline runs = 54 min. - 30 min. = 20 minutes
Therefore the equation for Jacqueline's speed = Distance/Time we have
Jacqueline's pace = 3.2 miles/20 minutes = 0.16 miles/minute
Therefore Jacqueline's pace = 0.16 miles/minute
The equation for Jacqueline's pace in miles/minute is presented as follows
Jacqueline's pace in miles/minute = Time of running/Distance
Jacqueline's pace in miles/minute = 1/0.16 miles/minute = 6.25 minutes/mile.

What is the circumference of the circle? Use 3.14 for .
r = 6.4 cm
© 20.096 cm
040.192 cm
0 200.96 cm
401.92 cm
Answers
Answer:
40.192 centimeters
Step-by-step explanation:
The circumference of a circle can be found using:
c= pi* diameter
First, we must find the diameter. The diameter of a circle is twice it’s radius.
d=2*radius
The radius of the circle is 6.4 centimeters. Substitute 6.4 for the radius.
d=2*6.4
d=12.8
Now we know the diameter. We can substitute 12.8 for diameter in the circumference equation.
c=pi*diameter
c=pi*12.8
We also know we are using 3.14 for pi, so we can substitute 3.14 for pi.
c=3.14*12.8
c=40.192
Use appropriate units: centimeters
c=40.192 centimeters
The circumference is 40.192 centimeters.
So the right answer is 40.192 cm

Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
Answers
Answer:
The price of a drink is $7.25
Step-by-step explanation:
Let d represent the price of a drink
let p represent the price of a popcorn
6p+12d=118.50 equation 1
p+6d=48.75 equation 2
multiply both equation 1 by 2
multiply equation 2 by 4
12p+24d=237 equation 3
4p+24d=195 equation 4
subtract equation 4 from 3
8p=42
p=42/8
p=$5.25
Substitute for p in equation 1
(6*5.25 )+12d=118.50
31.5 +12d=118.50
12d=118.50-31.5 0

A pair of shoes that originally cost $79 are on sale for 35% off. Does the expression 0.65(.79) represent the sale price of the shoes (in dollars)? explain your reasoning
Answers
Answer:
0.65(79) represents the correct sales price of the shoes (in dollars).
Step-by-step explanation:
As per question, discount offered on cost price = 35% and
Cost Price = 79$
Calculating discount :
Discount on cost price = [tex]35\% \times 79[/tex]
[tex]\Rightarrow \dfrac{35}{100} \times 79[/tex]
Now, it is know that we have to subtract the discount from cost price to get Sale Price:
[tex]\text{Sale price = Cost price - Discount on cost price}[/tex][tex]\Rightarrow \text{Discounted price = } 79 - \dfrac{35}{100} \times 79\\\text{Taking 79 common}\\\Rightarrow 79(1-0.35)\\\Rightarrow .65(79)[/tex]
Hence 0.65(79) represents the correct sale price of the shoes in dollars.
