8) The bill for labor at $13 per hour was at leastt $52

13x >= 52
x >= 4

So the labor was no less than 4 hours

-----------------------------

9) The quotient when dividing by -3 is greater than 5.

x/(-3) > 5
x > -15

-------------------------------

10) The 10-km race time of 88 minutes was twice as long as the winner's time.

The winner's time is 44 minutes

-------------------------------

11) A savings account increased by $50 is now more than $400.

x + 50 > 400
x > 350

---------------------

12) Seven times a number is less than 84.\

7x < 84
x < 12

----------------------

13) The house sold for $85,000. This is at least four times the original purchase price.

4x >= 85000
x >= 21250

-------------------------

15) b+9< or equal to 16

b + 9 <= 16
b <= 7

---------------------------

Define a variable and write an equation or inequality. Then solve.

18) Brisa delivers pizza for Mama's Pizzeria. Her average tip is $1.50 for each pizza that she delivers. How many pizzas must she deliver to earn at least $20 in tips?

a. What is being asked?

How many pizzas must she deliver to earn at least $20 in tips?

=========

b. What does the phrase at least $20 mean?

You must earn no less than $20

=========

c. Write an equation or inequality that describes the problem.
Solve.

1.5x >= 20
x >= 13.3333

but since you can't deliver a (1/3) of a pizza, she needs to deliver 14 pizzas

=============

d. Can your answer be anything other than a whole number? explain.

The true answer is a mixed number, but since you can't deliver a fraction of a pizza, since they only come in wholes, your answer would have to be a whole number.

i must say that i agree with everyone else here, and this sounds a lot like homework, and you need to do your homework by yourself. or you need to ask your teacher and see if they can set you up with a tutor.
