Answer 1

The ones where you designate an answer are all correct. Give your best answer for the remainder.

Answer 2

#3
4x + 8y - 3x + 2 y
= 4x - 3x + 8y + 2y
= x + 10y

the others from #1 to #12 are correct

#13
let number of bottles in a case be x
so you have 4x + 8 bottole
4x+8 = 104
4x = 96
x = 24

#14 , ok

#15
z – 4 > 9
add 4 to both sides
z > 13

#16

q + 7 ≤ – 15 , subtract 7 from both sides
q ≤ -22

#17
-3y > 9 , divide by -3, so you MUST reverse the inequality sign
y < -3

#18
k/5 ≥ -4 , multiply both sides by +5
k ≥ -20

#19
4g – 8 < 20
4g < 28
g < 7

#20
v/-2 + 12 ≤ 8 , subtract 12
v/-2 ≤ -4 , multiply by -2, reverse inequality sign
v ≥ 8

For the most part, when working with inequalities, pretend they are equations and perform the same steps, EXCEPT when multiplying or dividing by a negative, you must reverse the inequality sign.
This is usually your last step
