Answer:
x = 2
Step-by-step explanation:
5-2x = -4x+9
5+(-2x+4x) = (-4x+4x)+9 [Add 4x to each side to get ride of 4x on the right]
5+2x = 9
(5-5)+2x = (9-5) [subtract 5 from both sides to get rid of 5 on the left]
2x = 4
2x/2 = 4/2 [Divide each side by 2 to get x alone]
x=2
The solution to the equation 5 - 2x = -4x + 9 is x = 2.
Here, we have,
To solve the equation 5 - 2x = -4x + 9 step by step, we will combine like terms and isolate the variable x.
Here's how:
Start by simplifying both sides of the equation by combining like terms:
5 - 2x = -4x + 9
The left side has no like terms to combine, so we move to the right side:
-2x + 4x = 9 - 5
Simplifying further:
2x = 4
Now, we want to isolate the variable x.
To do that, we need to get rid of the coefficient 2 that is multiplied by x.
We can achieve this by dividing both sides of the equation by 2:
(2x)/2 = 4/2
Simplifying further:
x = 2
We have found the solution for the variable x.
Therefore, the solution to the equation 5 - 2x = -4x + 9 is x = 2.

The diameter of a circle is 3ft find its area to the nearest 10th
Answer:
6ft
Step-by-step explanation:
the 3 ft is multiple to 3
Answer:
A ≈ 7.1 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = πr² ( r is the radius )
Here diameter = 3 , then r = 3 ÷ 2 = 1.5 , then
A = π × 1.5² = 2.25π ≈ 7.1 ft² ( to the nearest tenth )
5) Emily woks Monday through Friday at a rate of $16.12 per hour. She takes a 1-hour lunch break. If she
clocks in each day at 6:15 A.M. and leaves at 4:15 P.M., what is her total pay for the week? (show your
work)
Answer: $725.40
Step-by-step explanation:
6:15A.M. - 4:15 P.M. = 10 hours - 1 hour lunch = 9 hours/day
$16.12hr*9 hours = $145.08 per day
Monday thru Friday = 5 days
$145.08 * 5 = $725.40 per week

Larry has three times as many pencils as Ben. Dejuan has four less than the number of pencils as Ben. Write the expression that would be the total number of pencils for all three of them.
Answer:
The total number of pencils for Larry, Ben and Dejuan is expressed as:
5B - 4
Step-by-step explanation:
Let B represent the number of pens Ben has.
》Ben = B
》Larry = 3 × B = 3B
》Dejuan = B - 4
∴ Total number of pencils for the three of them
= B + 3B + (B - 4)
= 5B - 4

A square pool has an area of 169ft^2 . What is the side length of the pool?
Area of a square is side ^2
To find the length of the side using area find the square root of the area.
Side length = sqrt(169)
Side length = 13 feet
Answer:
13 ft
Step-by-step explanation:
The area of a pool is length × width (l × w) , but the length and width are the same so I'll use [tex]b[/tex] representing both length and width:
A = l × w
A = [tex]b^{2}[/tex]
Area of the pool is 169
169 = [tex]b^{2}[/tex]
[tex]b[/tex] = [tex]\sqrt{169}[/tex]
[tex]b[/tex] = 13

Answer:
m<DEF = 47°
Step-by-step explanation:
Given:
m(DEF) = 266°
Required:
m<DEF
Solution:
m<DCF = ½(m(DEF)) (Inscribed angle theorem)
Substitute
m<DCF = ½(266°)
m<DCF = 133°
Opposite angles in an inscribed quadrilateral are supplementary.
Therefore,
m<DEF = 180° - m<DCF
m<DEF = 180° - 133°
m<DEF = 47°

Hello!
The slope equation is y = mx + b
mx is the slope and b is the yintercept.
4. y= -3x + 5
See where I put the slope and y intercept above?
Those are where the numbers go in that equation.
5. 3x + y = 5
The standard for equation is: Ax + by = c
y = -3x + 5
we need to make the equation look like the standard form equation.
y = -3x + 5
lets add 3x to both sides
The answer is 3x + y = 5
6. m = [tex]\frac{3}{2}[/tex]
We need to use this formula: [tex]m=\frac{y2-y1}{x2-x1} \\\\\\[/tex]
The points said are: (2, 5) and (4, 8)
[tex]m=\frac{8-5}{4-2}[/tex]
m = 3/2
M is the slope.

If BD = BC , BD = 5x - 26, BC = 2x+1, and AC = 43, find AB
Answer:
BD is congruent to BC. BD=BC
BD = 5x – 26, BC = 2x + 1, and AC = 43
To find out , we need to find BC first . For that we have to find out x
WE know that BD=BC, using that we solve for x
Now we plug in 9 for x and find out BC
BC=2x+1
BC=2(9)+1
BC=19
We know AC= 43
AC=AB +AC
43=AB+19
subtract 19
AB = 24

The ratio of students to adults on a field trip is 7 to 1. Which table correctly represents this ratio?
Andrew Is riding his bike. He biked a distance of 14 miles at a rate of 7 mph. using the distance formula, d = rat, solve for Andrews time in MINUTES.
(9th grade Algebra 1)
d = rt ( d = distance, r = rate (speed) and t = time)
14 = 7t
Divide both sides by 7:
t = 14/7
t = 2 hours
1 hour = 60 minutes.
2 hours x 60 = 120 minutes total.
120 minutes
Step-by-step explanation:
14 divided by 7 is 2 (hours). This means that Andrew biked for 2 hours at a pace of 7mph. Two hours is equal to 120 minutes.
the floor of a room is 12 m long and 6 m wide the floor of this room is to be fitted with tiles of dimension 10 cm x 2 cm what will the total expense in Rupees if the cost of tiling is 5 atile
Step-by-step explanation:
the price is 5 per tile ?
the area of the rectangular room is
12×6 = 72 m²
each m² has 100×100 = 10000 cm²
so, we have for the total area in cm²
72 × 10000 = 720000 cm²
one tile has 10×2 = 20 cm²
so, how many tiles will we need ?
720000 / 20 = 72000 / 2 = 36000 tiles.
so, if truly 1 tile costs 5 Rupees, then we have
36000 × 5 = 180000 Rupees as total costs.
Step-by-step explanation:
1 m = 100 cm
12 m = 1200 cm
6 m = 600 cm
Area of room = l × w
Area = 1200 × 600
Area = 720000 cm²
Area of tile = l × w
Area = 10 × 2
Area = 20 cm²
Total tile = 720000/20 = 72000/2 = 36000
Cost = 36,000 × 5
Cost = $ 180000

The ratio of the number of adults to the number of students on a field trip has to be 2:11. Last year there was 504 more students on a field trip. If the school is expecting the same attendance this year, how many adults have to attend the field trip?
Answer:
112 adults
Step-by-step explanation:
2x+504=11x
11x-2x=504
9x=504
x=56
The ratio is 2:11 so we multiply 56 by 2 and 11. The 2 represents the Adults and the 11 represents the students.
56*2=112 adults
56*11 = 616 students
Just to double check if you do 616-112 it is exactly 504, Therefore the amount of adults is 112.
Have a great day!
