Question

A) List the Steps of the operations for each number trick B) Simplify the expression (If possible)5(x+7)/3

Answer 1

a)

The expression given is:

$\frac{5(x+7)}{3}$

From this we can see that:

7 is added to a number, x

Then the whole thing is multiplied by 5 as shown by the parenthesis around it

Then the whole thing is divided by 3

So, the steps would be:

• Add 7 to the number

,

• Multiply by 5

,

• Divide by 3

b)

In order to simplify, we firsst distribute the 5:

$\begin{gathered} \frac{5(x+7)}{3} \\ =\frac{5x+35}{3} \end{gathered}$

This can be the final form, or we can divide the two terms by 3 and leave it added together:

$\begin{gathered} \frac{5x+35}{3} \\ =\frac{5x}{3}+\frac{35}{3} \end{gathered}$
