Which phrase best represents the following:

                            2n + 10
10 increased by a number
The sum of a number squared and 10
10 more than twice a number
A number squared plus 10
Which phrase best represents the following:
                      2x - 8
A number squared less than 8

Solve: - 3 = t - 4
                   4
t=
Solve: 3x  + 7= 28
x=
Solve:   4h - (-6) = -10
h=
Select ALL of the steps needed to solve the equation:
add 3 to both sides
 subtract 3 to both sides
multiply by 5 on both sides
divide  both sides by 5
5a + 3= 18
What is the first operation in solving this equation:
                           
                               3+ 2x= -7
subtract 3 on both sides
multiply both sides by 2
divide both sides by 2
add 3 to both sies
