What review words exactly?
Answer:
30
Step-by-step explanation:
Equation y = 3x + 210
if y = 10x
10x = 3x + 210
or, 10x - 3x = 3x + 210 - 3x
or, 7x = 210
or, x = 210 ÷ 7
or, x = 30
Answer:
C) 1050π cm²
Step-by-step explanation:
Surface area of a cylinder = 2πrh + 2πr²
radius, r = 3.5cm
Height, h = 4 cm
Surface area of a cylinder = 2πrh + 2πr²
= 2 * π * 3.5 * 4 + 2 * π * 3.5²
= 28π + 2π * 12.25
= 28π + 24.5π
= 52.5π cm²
Surface area of a cylinder = 52.5π cm
There are 20 bars of soap
Total plastic Emily needs for 20 bars of soap = surface area of each soap × 20
= 52.5π cm² × 20
= 1,050π cm²
I think that it would be the sum of all of the prices put together. 2505?
