Answer:
10
Step-by-step explanation:
25% is 25 over 100 = 1 over 4 of a number (% means "out of 100")
Setting the number as x means x * 1 over 4 = 2.5
To find x we will divide both sides by 1 over 4, which is also multiplying by 4
2.5 * 4 = 10
4a+7b-12c-8a-9b+12d
Now you have to combine like terms, so a and a, B and B etc.
4a-8a=-4a
7b-9b=-2b
No more like term
-4a-2b-12c+12d
Have a nice day
