Answer:
-4 in
Step-by-step explanation:
4 inches underground, assuming that ground level is 0, is negative four inches.
X + 8x = 81
9x = 81, x = 9
y = 8(9), y = 72
Solution: (9, 72)
to solve for j first you need to cross multiply;
j × 35 = 42 × 55
35j = 2,310
j = 2,310 ÷ 35 (did the inverse operation)
j = 66
