Answer:

4 (-1 + 2 x)

Step-by-step explanation:

Simplify the following:

9 x - (x + 4)

Ann [662]

Answer:

Step-by-step explanation:

Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags

The above provides 10pounds of potting soil already

Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil

We know that 1 bag contains 5/8 pounds of potting soil

x bags contain 3 pounds of potting soil

On cross multiplication we get

\frac{5x}{8}=3

x = \frac{24}{5}

since x is an integer x = 5 bags  

Note that an extra amount of soil will be remained unused
