The mixed number is 1 and 7/8 because 15 minus 8 equals 7/8 and since you went over the whole (8/8) it is 1 plus 7/8 which equals 1 and 7/8.
It's okay that you might not be good in math that's why we will help.
Lol i sound like a whole teacher
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
For the first Q the answer is the first square on the left 10 miles divided by 12 hours = 0,83 miles
And the second Q goes with the last square 12 hours divided by 10 miles = 1.2 h which in minutes is 72 minutes or 1h and 12 minutes.
9 is the answer negatives cancel out creating positve
