Let's solve the inequality.

x - 5 >= -2

Add 5 to both sides:

x >= 3

The solution of the inequality is the number 3 and all numbers greater than 3.

Since the inequality symbol is "greater than or equal to" which includes "equal to", draw a solid dot on 3. Because of the "greater than" part, you need numbers greater than 3, so color to the right of 3.

The correct answer is choice B.

A used bookstore sells hardback books and paperback books.A hardback book costs $11, including tax.A paperback book costs $5, in
Ket [755]

Answer:

D.5

Step-by-step explanation:

You can write the following equations from the information given:

y=x+3 (1)

11x+5y=47 (2)

x is the number of hardback books

y is the number of paperback books

You can replace (1) in (2):

11x+5(x+3)=47

11x+5x+15=47

16x=47-15

16x=32

x=32/16

x=2

Then, you can replace the value of x in (1) to find the value of y:

y=2+3

y=5

According to this, the answer is that Jamal bought 5 paperback books.
