We are given with:
Average height of plants to be at least 73 inches
Three plants with heights of
70, 71, 72
The inequality that can be used to determine the possible heights of the fourth plant is:
(70 + 71 + 72 + x) / 4 ≥ 73
Solving for x
x ≥ 79
120-36 = 84 <==== what he has left
84/120×100% = percentage of what he has left
70% = percentage aka answer.
The student is off by a power of 10
The answer is 3 x 10^12
Answer:
-9
Step-by-step explanation:
do distributive property first to eliminate the parenthesis.
5h + 22 - 2h = -5
combine like terms
3h + 22 = -5
move the 22 over by subtraction
3h = -27
divide
h = -9
