Question

Can any body help with the word problems

Answer 1

1) 8x - 9

2) 5x - 2

Explanation:

1) Given 8 times the difference between a number x and 9.

This means we should have:
`$ 8(x - 9) $`

Now using the distributive property we distribute 8 to x and 9 like:

`$ 8x - 72 $`. Thus the answer.

For 2) All the expressions except 4 equals
`$ 5x - 10 $`. The last option is
`$ 5x - 2 $`. Thus the answer.
