Question

Can any body help with the word problems

Answer 1

Answer:

1) 8x - 9

2) 5x - 2

Step-by-step 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.
