Mathematics

Answer:

x = -5

Step-by-step explanation:

Start by adding the 5x to each side of the equation to the left to get...

-25 = 5x + 25 + 5x

Then you would add 25 to each side of the equation to get...

0 = 10x + 25 + 25

Adding on, you would simplify this step to get...

0 = 10x +50

You would now have to make the x variable on one side alone so you would subtract 50 from both sides of the equation again to get...

-50 = 10x

Finally you would divide both sides of the equation by 10 to get x alone...

-50/10 = 10x/10

And simplify that to get...

x = -5

Help me please <br><br> Find the average of these numbers.<br><br> 15, 12, 17, 13, 20, 19
Lynna [10]
We would find the mean. So:
15 + 12 + 17 + 13 + 20 + 19 = 96
Divide the sum by the amount of numbers added together. 
So: 96/ 16
The mean or average is 16

Mick paid $2.94 in sales tax on an item that cost $42.00 before tax. At that rate, how much would he pay in slaes tax for an ite
alexdok [17]

For an item that cost $ 42, Mick paid $2.94 in sales tax. So percentage of sales tax is

\frac{2.94}{42} *100 = 7%

And we have to find the sales tax that he paid for an item that cost $58, and for that , we have to find 7% of 58 , that is

= \frac{7}{100} *58 = $4.06

So he pays a sales tax of $4.06 .
