Answer:
1. unknown
2. 1/4h+3
3. a=2
4. x=8
5. p=30
Step-by-step explanation:
32k+24= not sure where you are going with this.
(3/4h+4)-(1/2h+1). you can rewrite it so it shows numbers and variables together.
(3/4h-1/2h) -(4+1).
3/4h-1/2h = 1/4h. &
the subtract changes the plus to minus, so it is 4-1= 3
So, 1/4h+3.

5a-12=-2
you want to have the letter a, by itself on one side of the = sign.
to do that, you need to do the opposite on both sides.
start with -12. (add 12 to both sides)
5a -12 + 12=-2+12
5a=10
then divide both sides by 5
5a/5=10/5
a= 2

-5(x-4)=-30
take -5 times x and -5 times -4
-5x + 20=-30 (when you multiply a negative times a negative, it is a positive. )
opposite to both sides again. -5x+20-20=-30-20
-5x=-40
then divide both sides by -5
-5x/-5=-40/-5
x=8

The equation is P=21+9. P for points Alice has. p=30
