Answer:the first one
Step-by-step explanation:
Subtract the like terms to get your answer of y^2 - 4y - 6
This seems to be dividing by 4, so the next numbers are 20, and then 5. If there is a 3rd, it's 1.25
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:
w=9
