Answer:
10y³
Step-by-step explanation:
y appears 3 times.
Which means y is multiplied by itself 3 times.
Then, simplify 5 x 2, which is 10, then put y3 after 10.
Let d be the number of days and h be the height
h = 13 + 0.6d
Answer: (a) h = 13 + 0.6d
Given height = 0.208m, find d:
0.208m = 20.8 cm
20.8 = 13 + 0.6d
0.6d = 20.8 - 13 = 7.8
d = 7.8 ÷ 0.6 = 13
Answer: (b) 13 days
