Combine like terms. 3y + y + 6y A. 10y B. 8y C. 9y-y D. 2y
2 answers:
First off,like terms are value with the same unknown.
For example,in the equation 2x+3y+5y+4x,
The like terms would be 2x and 4x, with the same unknown x,
and the other like terms would be 3y and 5y with the same unknown y.
In this case (3y+y+6y), as they all have unknown y, they all are like terms.
To combine,we can simply add them together:
Therefore the answer is A. 10y.
Hope it helps!

sorry this might not be very helpful. I haven't don't this since last year. You basically have to work backwards. so plug in 972 for V and then do (3/4)×3.14.
then take the answer u got for ^^ and divide it by 2? not sure.
