Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15

Step-by-step explanation:
[tex]C = 400 \sqrt[3]{n} + 200 \\ \\ plug \: C =5800 \\ \\ 5800 = 400 \sqrt[3]{n} + 200 \\ \\ 5800 - 200 = 400 \sqrt[3]{n} \\ \\ 5600 = 400 \sqrt[3]{n} \\ \\ \frac{5600}{400} = \sqrt[3]{n} \\ \\ 14 = \sqrt[3]{n} \\ \\ {(14) }^{3} = {(\sqrt[3]{n})}^{3} \\ (cubing\: both\: sides) \\\\ 2,744 = n \\ \\ n = 2,744[/tex]
Two groups are hiking at about the same speed . Mario’s group hikes for 2.5 hours Seemas group hikes for 4.7 hours and covers 8.8 more miles . How fast are the kickers going ? Solve the equation below to find out . 4.7x=2.5x+8.8
Answer: 18.8 miles
Step-by-step explanation:
Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:
4.7x = 2.5x + 8.8
Collect like terms.
4.7x - 2.5x = 8.8
2.2x.= 8.8
x = 8.8/2.2
x = 4
To know how fast the kickers are going will be
4.7x = 4.7 × 4 = 18.8 miles

A pizza store sold 36 pepperoni pizzas in a day, which was 24% of their pizza sales.
What was the total number of pizzas sold that day?
Answer:
150 pizzas
Step-by-step explanation
36 pizzas are equivalent to 24% so i divided both sides by 4 which gave me 9 pizzas for 6% . But 6 cannot fully fit into 100 so it will have to be a decimal i did 100 divided by 6 so i would know what i would have to divide both sides by which gave me 50/3 which was 16.66666667 which when i times by 9 by it gave me 150 pizzas

When looking at a graphed System of Equations,
how do you determine which line is the better
deal?
Answer:
Step-by-step explanation:
So, if we are looking to save money, then it would probably be a good choice to go for the least steepest line. Assuming Money stands for the Y axis and Quantity stands for the X axis, then looking at the least steepest line means the lowest Y axis, which translates to the least amount of money.

(a) An angle measures 51°. What is the measure of its complement?
(b) An angle measures 113°. What is the measure of its supplement?
Step-by-step explanation:
For a
Let the another angle be x then
x + 51° = 90° {being complementary angles }
x = 90° - 51°
x = 39°
For b
Let the another angle be x then
x + 113° = 180° {being supplementary angles }
x = 180° - 113°
x = 67°
Solve the system by substitution.
y = 8x
y = 4x + 8
Answer:
y = 16
x = 2
Step-by-step explanation:
y = 8x
y = 4x + 8
then, by substitution:
8x = 4x + 8
8x - 4x = 8
4x = 8
x = 8/4
x = 2
y = 8x
y = 8*2
y = 16
Check:
y = 4x + 8
y = 4*2 + 8
16 = 8 + 8
Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) − 210°. Find m∠Y.
Answer:
m∠Y = 50°
Step-by-step explanation:
let 'm' = m∠Y
m∠S + m∠Y = 90 (complementary)
5m - 210 + m = 90
6m = 300
m = 50

two angles of a triangle measure 29 degrees and 12 degrees what is the measure of the third angle?
Answer:
The measurement of the third angle would be 139 degrees.
Step-by-step explanation:
Using the triangle sum theorem, you already know that all interior angles of a triangle add up to 180 degrees. So since you already have two angle measurements, all you have to do is add them together and subtract them from 180 degrees. In this case it is 29+12, which equals 41. Now you subtract that from 180 and get 139.

A recipe calls for 3/2 cups of sugar to make 24 cookies. How many cups of sugar are needed to make 60 cookies?
Answer:
3.75 or 3 and 3/4
Step-by-step explanation:
3/2 Cups = 24 Cookies
?Cups 60=Cookies
Divide 60 by 24, which is 2.5
2.5x3/2 is 3.75 or, in fraction, 3 and 3/4
3 and 3/4 cups of sugar and needed to make 60 cookies
Marcus is building a fence around his rectangular backyard. The length of his backyard is 75 3/4 ft, and the width is 81 1/4 ft. If the fence is 3/4 finished, how much fencing is left to complete?
Answer:
Step-by-step explanation:
Answer:
4,923.75ft²
Step-by-step explanation:
The area of the backyard = Length * width \
Area of the backyard = 75 3/4 * 81 1/4
Area of the backyard = 303/4 * 325/4
Area of the backyard = 6,154.6875ft²
If 3/4 of the fence is finished, the area of the finished part is expressed as;
Finished part = 1/5 * 6,154.6875
Finished part = 1,230.9375ft²
Part left unfinished = 6,154.6875-1,230.9375
Part left unfinished = 4,923.75ft²
Answer: 235.5
Step-by-step explanation:
75 3/4= 75.75 (L). 81 1/4= 81.25 (W)
Perimeter= 314 3/4 of 314 is 235.5

Answer: 11 more i think
Step-by-step explanation:
Your grandmother has given you a gift of $1500 for your birthday. You are thinking about your future and
considering two different options on how to manage your money. Option A: You take all of your $1500 and
deposit it into a savings account that has a 5% interest rate per year. Option B: You spend $500 on a new
Apple Watch and deposit the remaining $1000 in a savings account that has a 5.5% interest rate per year.
.
Which account would have the most in 10 years? 20 years? Mathematically, explain your reasoning.
Which option would you choose and why?
.
Answer:
B
Step-by-step explanation:
if you put the rest of your money in a savings account you can use that money for your college fund or maybe buy a car ect.
Answer:
OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for "thinking about your future"
Step-by-step explanation:
In the absence of any more information, I am going to assume that Simple Interest applies. (see attached)
hence the applicable formula is:
A = P(1+rt), where
A = final amount after t years
P = Principal (beginning) amount ($1500 for option A and $1000 for option B)
r = annual interest rate (5% = 0.05 for option A and 5.5% = 0.055 for option B)
t = time (we are asked to evaluate t = 10 years and t = 20 years)
For option A :
P = $1500 and r = 5% = 0.05
A = P(1+rt)
A = 1500 [ 1 + (0.05)t]
at 10 years: A = 1500 [ 1 + (0.05)(10)] = $2,250
at 20 years: A = 1500 [ 1 + (0.05)(20)] =$3,000
For option B :
P = $1000 and r = 5.5% = 0.055
A = P(1+rt)
A = 1000 [ 1 + (0.055)t]
at 10 years: A = 1000 [ 1 + (0.055)(10)] = $1,550
at 20 years: A = 1000 [ 1 + (0.055)(20)] = $2,100
Comparing all the 4 results above, we can see that OPTION A yields the most money at 10 and 20 years. Hence Option A is the better choice for long term returns.

The slope of the line below is -2. Use the cordinates of the labeled point to find a point-slope equation of the line
Answer:
We can not see the image, so i will answer this in a general way.
We know that a linear equation can be written as:
y = a*x + b
Where a is the slope, and b is the y-intercept.
In this case, we know that this line has a slope equal to -2, then the line is:
y = -2*x + b
Now, suppose that in the image we can see that this line passes through the point (j, k)
Then we can replace x by j, and y by k in the line equation, to get:
k = -2*j + b
Now we can solve this for b:
b = k + 2*j
Then we can conclude that a line with a slope equal to -2, that passes through the point (j, k) is:
y = -2*x + (k + 2*j)
IS THIS A LINEAR FUNCTION? YES OR NO
