Answer:

x=142, y=-360. (142, -360).

Step-by-step explanation:

5x+2y=-10

3x+y=66

----------------

5x+2y=-10

-2(3x+y)=-2*66

-----------------------

5x+2y=-10

-6x-2y=-132

-------------------

-x=-142

x=142

3(142)+y=66

426+y=66

y=66-426

y=-360

Answer:

1- 5x+2y+−2y=−10+−2y

5x=−2y−10

\frac{5}{5}= \frac{-2y-10}{5}

x= \frac{-2}{5}y-2

2-  3x+y+−y=66+−y

3x=−y+66

\frac{3x}{3} = \frac{-y+66}{3}

x=\frac{-1}{3}y+22

Step-by-step explanation:

goldenfox [79]
160 square inches

if the block is cut after it’s been painted, two sides with the same measurements don’t have glitter on them. you find the area of the one rectangle and multiply it by 2 as follows:
A = length • width
A = 10 • 8 = 80
area that needs to be covered = 80 • 2 = 160 square inches
