Ok so you have to do distributive property which will give you 10x-40+15=-15
Then the next step you have to do is minus 15 from each side so you get 10x-40=0 then you add the 40 to the other side so you get 10x=40 then you move the ton to the other side but when you do that you will wright it under the 40 so then you will have 40/10 and that will give you x=4

I hope this helps you

5(2x-8)+15=-15
First do what is in parenthesis!
You have to multiply "2x and 8 both by 5 because it says 5 of 2x-8's
Then you get:
10x-16+15=-15
Now let's solve -16+15
We then get -1. 
10x-1=-15
We need to isolate x to one side so in order to do that we need to add one to both sides, because -1+1 equals 0.
Then we have 
10x=-14
Now we really want x to be the only thing on the left side, so we HAVE to divide everything by 10 on both sides.
x=-1.4

kvasek [131]

Answer:

x=4C/πs^2

Step-by-step explanation:

C=1/4πs^2x

1) Divide both sides by π and s^2:

C/πs^2=1/4x

2) Multiply both sides by the reciprocal of 1/4: (4)

marin [14]

Step-by-step explanation:

The equation 0.5s+ 9.99=30 describes the situation.

9.99 is the fixed amount

0.5 is the cost for each song download

30 is the maximum amount spend for a month

Here 's' represents the number of songs download

0.5s+ 9.99=30 means

0.5 times the number of songs plus the fixed cost 9.99 should be equal to 30 dollars.

The solution to this equation is s=40.02.

s= 40.02  means 40 songs can be downloaded as per the budget

Tresset [83]

Answer:

30.25

Step-by-step explanation:

All angles of a line must add up to 180. Since we already know that one angle is 90 degrees, we know that the other angles should add up to 90 degrees in order for all of the angles to add up to 180 degrees:

(3x-7)+(x+8)=90

4x+1=90

4x=89

x=22.25

22.25+8= 30.25
