Raymond buys bottles of water at $2.10 each and a large pizza at $12.99. The total cost was $21.39. How many bottles of water b did he buy? (1 point)

2.10b + 12.99 = 21.39; 4 bottles
2.10 + 12.99b = 21.39; 4 bottles
2.10c = 21.39 + 12.99; 6 bottles
21.39 – 2.10b = 12.99; 16 bottles


For #2, there is no -24.
Is #7 correct?
For #9, i don't know how to solve it.

    Read my response carefully. I didn't tell you the value of x.

    2.
    6x + 29 = 5
    6x = 5 - 29
    6x = -24

    7 is correct.
