Answer:
w=9
Step-by-step explanation:
Our equation is: 8w-15=57
Add 15 to both sides
-15 is now gone because we added 15 so it would be zero
and we have 72 because 15 plus 57 is 72
Now we have:
8w=72
Divide by 8 on both sides
8w cancels out to just w
and 72 divided by 8 is 9
And you're left with:
(X+3)(X+8)
In the attached file
100% of 180 = 180
25% of 180 = 45
-75% of 180 = -135
37.5% of 180 = 67.5
