To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 120 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 120, so we can write it down as 100%=120.
4. We know, that x% equals 371 of the output value, so we can write it down as x%=371.
5. Now we have two simple equations:
1) 100%=120
2) x%=371
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=120/371
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 371 is what percent of 120
100%/x%=120/371
(100/x)*x=(120/371)*x - we multiply both sides of the equation by x
100=0.323450134771*x - we divide both sides of the equation by (0.323450134771) to get x
100/0.323450134771=x
309.166666667=x
x=309.166666667
now we have:
371 is 309.166666667% of 120
Pizzas are circles. Area of circles is (pi)r^2.
Then find the cost per in.^2
Smallest cost per in.^2 is better buy.
Answer:
100ft
Step-by-step explanation:
H over S
H over 125 then 4 over 5
cross Multiply would give you
5H = 500
500 ÷ 5 is 100
Answer:
r=3
Step-by-step explanation:
simplify each side
4r+17=6r+11
Subtract 4r from both sides.
17=2r+11
Subtract 11 from both sides
6=2r
divide both sides by 2
3=r
Answer:
D. Subtract 9y from both sides of the equation.
Step-by-step explanation:
A. Divide both sides of the equation by 36.
B. Multiply both sides of the equation by 6.
C. Add 9y to both sides of the equation.
D. Subtract 9y from both sides of the equation.
Given:
9y - 6x = 36
To solve for x
Step 1: subtract 9y from both sides
9y - 6x - 9y = 36 - 9y
- 6x = 36 - 9y
Step 2: Divide both sides by -6
- 6x / -6 = (36 - 9y) / - 6
x = (36 - 9y) / - 6
The answer is
x = (36 - 9y) / - 6
