Answer:
6 pushups
Step-by-step explanation:
We'll do the distribute property for both.
1/2x6x=3x
1/2x-10= -5
SO....
3x-5+ -4x +30
Which is
-x + 25 or 25-x.
Hope this helps!
The 1st and 3rd choices are irrational. The other 2 are rational. Irrational numbers are numbers that you can't make a simple fraction out of.
To solve this problem just do the following,
x+9=-12
-9 -9
x=-21
Check
-21+9=-12 = True
Hope this helps!=)
