Answer:

B 2x-31 = -2x-31

Step-by-step explanation:

A is exactly the same on the left side as the right so it has infinite solutions

B 2x-31 = -2x-31

 Add 2x on each side

2x+2x-31 = -2x+2x-31

4x -31 = 31

Add 31

4x =62

This has one solution

C 2x+31 = 2x-31

Subtract 2x from each side

31 = -31

This is never true so it has no solutions

D 2x-2 = 2x-31

Subtract 2x from each side

-2 = -31

This is never true so it has no solutions

What comes after 1 as a mixed number on a number line
dalvyx [7]
I'm going to assume that you know what an integer is, and that 1 is an integer. I'm also going to assume you've learned what a mixed number is. If not, a mixed number is a decimal changed into a fraction. So rather than write "1.5" as an answer, you can leave it as a fraction and get 1 1/2.

The same thing can be done to any type of rational fraction. 1.1, 1.2, 1.3, etc. If you choose to use any of those, the numerator will be the number you choose to do (1,2,3, etc) over 10. 

I hope I was able to help. Best of luck!
