Answer 1

ok

Answer 2

welcome to openstudy

Answer 3

A) a - 9 = 20

Answer 4

when you solve equations, you can do operations on them, but what you do to one side of the equation, you have to do to the other side..

try adding 9 to both sides of that equation

a - 9 = 20

Answer 5

a = 29

Answer 6

yep, you got that one

Answer 7

You can do the same thing with addition and subtraction with inequalities....

b - 9 > 20 ...........try adding 9 to this one on both sides also

Answer 8

29

Answer 9

b > 29, remember to keep all the information

Answer 10

so for part C, what did you do to both part a and part b, that was similar

Answer 11

I subtract both of them and i got 20. Like 29- 9 = 20.
