Here are the 2 questions, thanks ! :)

Step-by-step explanation:

10)

So we know that the full length is 19+2x-18 and it's equal to the bottom, which is 4x-29. Just set up an equation like this:

19+2x-18=4x-29

Simplify

1+29=4x-2x

30=2x

x=15

14)

In this case, we know EG is the same length as x+23. By subtracting 12 from 26+x, we get EF's length and can add it to 14+x to get EG.

26+x-12=14+x

14+x+14+x=28+2x

x+23=2x+28

23-28=x

x=-5

Sorry this took a while.

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
