Hey!
------------------------------------------------
Steps To Solve:
8y - 3 = бу + 17
~Subtract 8y to both sides
8y - 3 - 8y = бу + 17 - 8y
~Simplify
-3 = -2y + 17
~Subtract 17 to both sides
-3 - 17 = -2y + 17 - 17
~Simplify
-20 = -2y
~Divide -2 to both sides
-20/-2 = -2y/-2
~Simplify
10 = y

Answer:
D. 13 1/2
Step-by-step explanation:
2/3 x -2 = 7
2/3 x -2 + 2 = 7 + 2
2/3 x = 9
x = 9 (3/2)
x = 27/2
x = 13 1/2
Answer:
72. If the second 3cm has some relevance, leave a note and I'll come back and modify my answer.
Step-by-step explanation:
Givens
L = 6 cm
W = 3 cm
H = 2 cm
I don't know what the extra 3 cm is for.
Formula
SA = 2*L*W + 2*L*H + 2*H*W
SA = 2*6*3 + 2*6*2 + 2*2*3
SA = 36 + 24 + 12
SA = 72
