What is the solution of the inequality r/5 less than or equal to 6?

Answer 1

r must be less than or equal to 30. So the solution is r ≤ 30.

Answer 2

What is the solution of the inequality 7s not equal to 91?

Answer 3

To find the solution for the inequality 7s ≠ 91, we need to isolate the variable s.

Divide both sides by 7:
7s ≠ 91
s ≠ 91/7
s ≠ 13

Therefore, the solution to the inequality is s ≠ 13.

Answer 4

Solution of 4f greater than 36

Answer 5

To find the solution to the inequality 4f > 36, we need to isolate the variable f.

Divide both sides by 4:
4f > 36
f > 36/4
f > 9

Therefore, the solution to the inequality is f > 9.

Answer 6

While on vacation, a family will be driving 5 hours every day. They want to cover at least 240 miles each day. The inequality 5s greater than or equal to 240 expresses the average speed, s, they must maintain in miles per hour, What is the solution of this inequality?

Answer 7

To find the solution to the inequality 5s ≥ 240, we need to isolate the variable s.

Divide both sides by 5:
5s ≥ 240
s ≥ 240/5
s ≥ 48

Therefore, the family must maintain an average speed of at least 48 miles per hour to cover at least 240 miles each day.
