Hi friend
#24
y/9+5=0
Simplify to both sides
1/9 y+5=0
Now subtract 5 from both sides
1/9 y+5-5=0-5
1/9 y=-5
Multiply both sides by 9 so we can find the y value
9(1/9 y)= (9)(-5)
y=-45
The answer is A ( Your answer was not good)
#25
3b-7<32
First you need to add 7 to both sides
3b-7+7=32+7
3b<39
Now divide both sides by 3 so we can find the value for b
3b/3<39/3
b<13
The answer is A
#26
3p-16<20
Now we gonna do the same thing
Add 16 to both sides
3p-16+16<20+16
3p<36
Now divide both sides by 3
3p/3<36/3
p<12
The answer is C
#27
3p-6>21
Just do the same thing
Add 6 to both sides
3p-6+6>21+6
3p>27
Divide both sides by 3
3p/3>27/3
p>9
The answer is B
I really hope that's help and good luck :0
