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.

Answer: $x=45$

Simplify both sides of the equation

$x+1.2x+1=100$

$(x+1.2x)+(1)=100$ (Combine Like Terms)

$2.2x+1=100$

Subtract 1 from both sides

$2.2x+1-1=100-1\\2.2x=99$

Divide both sides by 2.2

$2.2x/2.2=99/2.2$

$x=45$
