8.40 ÷ 4 = 2.10, which is the price for those five stamps :)
5 stamps will cost $2.10
if twenty stamps cost 8.40, we want to find out how many five stamps cost.
20/5=4
we can use this to calculate
8.40/4=2.10, which is the price for those five stamps.

Distribute and combine like terms. Please show all of your work.<br><br> -5(3x + 7) - 4(x - 4) + 11

Varvara68 [4.7K]

For this case we have the following expression:

$-5 (3x + 7) -4 (x-4) +11$

For simplicity we follow the steps:

We apply distributive property to the terms within the parenthesis, bearing in mind that:

$- * + = -\\- * - = +\\-15x-35-4x + 16 + 11 =$

We add similar terms taking into account that equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed.

$-15x-4x-35 + 16 + 11 =\\-19x-8$

ANswer:

$-19x-8$
