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.

Find the roots of the following equations.<br> a) 4x+9=34<br> b) (x-4)(x+2)=0<br> c) 2x^2-6x+4=0
Masteriza [31]
A. 4x + 9 = 34
    <u>      - 9   - 9</u>
          <u>4x</u> = <u>25</u>
           4      4
            x = 6.25

B. (x - 4)(x + 2) = 0
    x - 4 = 0    U    x + 2 = 0
    <u>  + 4 + 4</u>          <u>    - 2  - 2</u>
         x = 4                 x = -2

C.          2x² - 6x + 4 = 0
    2(x²) - 2(3x) + 2(2) = 0
            <u>2(x² - 3x + 2)</u> = <u>0</u>
                      2             2
                x² - 3x + 2 = 0
                x = <u>-(-3) +/- √((-3)² - 4(1)(2))</u>
                                      2(1)
                x = <u>3 +/- √(9 - 8)</u>
                               2
                x = <u>3 +/- √(1)
</u>                            2<u>
</u>                x =<u> 3 +/- 1
</u>                          2
                x = <u>3 + 1</u>    U    x = <u>3 - 1</u>
                         2                      2
                x = <u>4</u>                 x = <u>2</u>
                      2                       2
                x = 2                 x = 1

Joseph had 7 1/4 ounces of candy to share with his friends. He gave them 2 4/5 ounces of candy when they came over to play video
OleMash [197]
7 1/4 - 2 4/5
Turn the denominator into a common denominator for both fractions:
7 5/20 - 2 16/20
To subtract easier, turn the fractions into an improper fraction:
145/20 - 56/20
Subtract the numerators:
145 - 56 = 89 ---> 89/20
Simplify (to get an answer of):
4 9/20
