Rewrite the equation so that the x term is on the left:

9 - 3x = -18

Move the number to the right and change the sign:

-3x = -18 - 9

-3x = -27

Change the sign of both terms:

3x = 27

Move the 3 to the right and change the sign:

x = 27 ÷ 3

x = 9 is your answer.

You are wrapping a gift box that is 16 inches long, 7 inches wide, and 9 inches tall. Find the amount of wrapping paper you need

Svetach [21]

Answer:

638 in.²

Step-by-step explanation:

Assuming you need to cover just the surface area of the box with no overlaps, and the shape is a rectangular prism, then you need to find the surface area of a rectangular prism.

SA = PH + 2LW

where

P = perimeter of base = 2(L + W),

H = height of prism

L = length of base

W = width of base

SA = 2(16 + 7)(9) + 2(16)(7)

SA = 638

Rearrange the equation so u is the independent variable. -12u+13=8w-3 <br><br> w= ___

Rama09 [41]

Answer:

w = $\frac{-12u+16}{8}$

Step-by-step explanation:

Reverse the equation placing w on the left side

8w - 3 = - 12u + 13 ( add 3 to both sides )

8w = - 12u + 16 ( divide both sides by 8 )

w = $\frac{-12u+16}{8}$
