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

eric can spend a maximum of $270 on office supplies. Each rem of paper costs $6. Each ink catridge costs $18. Which of the follo
Vladimir [108]
If we say A = ream of paper and B = cost of ink than we can set-up an expression to calculate when A is equal to a number what the number of B will be. Maximim of 270$ so anything we buy must be equal to this. Ream of paper cost 6$ each so 6A represents the number of reams bought since we said A is number of reams of paper. Ink Cartridges are 18$ each so 18B would represent this based on B = to cost of ink. Now setting up our equation 6A + 18B = 270 When A = 1 B = 14.67 Ink Cartridges When A = 1 Ream ofpaper

What is 1 and 1/4 minus 3/8?
matrenka [14]

Answer: 7/8

Step-by-step explanation:

You can change all the fractions to have equivalent denominators.

The Least Common Denominator of 1 1/4 and 3/8 is 8. Now we can change the fractions.

1 1/4 = 1 2/8 = 10/8.

3/8 = 3/8.

Now we can subtract. Subtract the numerators of the first fraction from the numerators of the second fraction, and the denominators oft he first fraction to the denominators of the second fraction.

10/8 - 3/8 = 7/8.

Therefore, 1 1/4 - 3/8 = 7/8; the fourth answer.
