<em><u>Hello there! :)</u></em>

<em><u>Answer:</u></em>

<em><u>x=7</u></em>

<em><u>*The answer must have a positive sign.*</u></em>

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you expand.

5(x-3)=5x-15

5x-15=x+13

Then, you add by 15 from both sides of an equation.

5x-15+15=x+13+15

Simplify.

5x=x+28

You subtract by x from both sides of an equation.

5x-x=x+28-x

Simplify by equation.

4x=28

Then, you divide by 4 from both sides of an equation.

\frac{4x}{4}=\frac{28}{4}

Finally, divide by the numbers from left to right.

28/4=7

<u><em>Final answer is x=7</em></u>

Hope this helps!

Thanks!

Have a nice day! :)

:D

the sales tax for an item was $30.10 and it cost $430 before tax. find the sale tax rate. write your answer as a percentage.
timurjin [86]
To find a percentage of a number, multiply by the decimal form of that percentage(20%=0.20). So, take the cost, $430, and multiply by common state sales tax (7% for me)---430 x 0.07 = 30.10  The sale tax rate is 7%.
