4(5x - 2) = 72<br> What do I do

Pepsi [2]

Answer:

x = 4

Step-by-step explanation:

4(5x - 2) = 72

Do the distributive property

20x - 8 = 72

Then add 8 to both sides to get 20x alone

20x - 8 = 72

+ 8 + 8

20x = 80

Then divide both sides by 20 to get x

$\frac{20x}{20} = \frac{80}{20}$

x = 4

The Smiths spend 11% of their budget on entertainment. Their total budget this year is $1,000 more than last year, and this year

son4ous [18]

Answer:

$365,400

Step-by-step explanation:

If their budget is $5,060 this year and its $1,000 higher, than we can say that last year was $4060. Next, we look at the 11%. Their entertainment is 11% of the total budget. This means the rest of the budget is 89%. Multiply $4,060 by 89 which gets you $361,340. Add this with the $4060 (the 11% left) and it's $365,400. (I'm not sure if my math is 100% correct, but I know these are the proper steps.)
