The inequality 12x+9 ≥ 21 represents the minimum rate Chanita have to swim on second day to complete the distance.
Step-by-step explanation:
Given,
Length of English Channel = 21 miles
Distance covered on first day = 9 miles
Time to complete remaining distance on second day = 12 hours
Let,
x be the distance covered per hour on second day.
Time to cover distance * Distance covered per hour + Distance on first day ≥ Total distance
12x+9 ≥ 21
The inequality 12x+9 ≥ 21 represents the minimum rate Chanita have to swim on second day to complete the distance.

It's where the altitudes all intersect. In a right triangle, the legs of the right triangle are the altitudes-- especially evident when the right angle is at the base. The altitude from the hypotenuse to the right angle also passes through the right angle.
Answer: 5 (estimate)
Step-by-step explanation:
x - 17 4/5 = -13 1/5
Estimate: x - 18 = -13
x - 18 + 18 = -13 + 18
x = 5
actual answer without estimating using exact numbers is 4 3/5 (so estimate is reasonable)
