D-10-2d+7 = 8 + d- 10 -3d
d-2d-10+7 = 8-10 +d -3d
-d-3=-2-2d
-d+2d=3-2
d=1

Final answer: C. d=1

D-10-2d+7 = 8 + d- 10 -3d

=> d -2d -10+7 = 8 -10 +d - 3d
=>-d - 3 = -2 -2d
=>-d+2d = -2 +3
<span>=> d = 1 ..

PLEASE HELP! Find the height of a cylinder with a surface area of 108 pi square meters. The radius of the cylinder is twice the

Naily [24]

Assuming the cylinder is closed at both ends
Surface area = 2 pi r^2 + 2 pi r h = 108

now h = r/2 so we have:-

2pi r^2 + pi r^2= 108

3 pi r^2 = 108
r^2 = 11.459
r = 3.385
so the height h = 1.693 m to nearest thousandth

Dvinal [7]

Answer:

20%

Step-by-step explanation:

A pair of jeans cost $45 before the sale.

The sale is taking $9 off of the original price.

Then

$45 - 100%

$9 - x%

Write a proportion:

$\dfrac{45}{9}=\dfrac{100}{x}$

Cross multiply:

$45\cdot x=9\cdot 100\\ \\45x=900\\ \\x=\dfrac{900}{45}\\ \\x=20\%$
