Solve for X: 1/3 (2x - 8)=4.

x = 10

Step-by-step explanation:

1/3 (2x - 8)=4.

Multiply each side by 3

1/3 *3(2x - 8)=4.*3

2x-8 = 12

Add 8 to each side

2x-8+8 =12+8

2x = 20

Divide each side by 2

2x/2= 20/2

x = 10

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

x+10

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
