2 (4 + x)

You multiply the number outside the parenthesis with the numbers inside

So you do 2 x 4 = 8

Then 2 x X = 2x

You keep the addition sign

so your answer in 8 + 2x

Adding, subtracting, multiplying, or dividing the numbers or letters that are the same

So 4x + 8x can be combined

4x + 8x + 12x

3x + 1 / 4y can not be combined

3x, 1, and 4y are all the same so you can't simplify the answer

First you move the decimal over two times on the percent so 17% would be .17

Then you do .17 x $5,000 on your google calculator

What answer do you get?

If you bought 10 shirts for $500, how much does one shirt cost?

You use division to solve.

500/ 10 = 50
