What is the sales tax on a $8.50 purchase if the sales-tax rate is 6.5% (6 1/2 %)?
konstantin123 [22]
The answer is $0.55

$8.50 is 100%.
x is 6.5%

8.50 : 100% = x : 6.5%
x = 8.50 : 100% * 6.5%
x = 0.5525
x ≈ $0.55

What is the answer to <br> -2x+2(5x+18)=-4
adell [148]

Answer:

x = -5

Step-by-step explanation:

-2x+2(5x+18)=-4

The first thing you would have to do is distribute the positive 2 with 5x and 18 so that means you would multiply those two number inside the parenthesis.

-2x+ 10x+ 36=-4              2(5x)=10x     2(18)=36

Now you combined like terms on the other side of the -4. So since -2x and 10x are like terms because of the variables you would do -2x+10x=8x. So now your equation is 8x+36=-4. So now you want you x by itself so you would subtract 36 on both sides so positive 36 subtracted by 36 is 0 now you subtract 36 to -4 so that equals -40 because you did -4-36=-40. So now you have 8x=-40 so now you divide both sides by 8x so -40/8=-5

x=-5
