Question

Which expression is equivalent to 15 y - 8 y​ ?

Answer 1

Answer:

D. The expression 5 y plus 2 y is equivalent to 15 y minus 8 y.

Step-by-step explanation:

first we unite like terms from the given problem, 15y - 8y which gives 7y

next we compare that answer to the two options, so 5y + 2y is 7y

BUT 9y - 3y is actually equal to 6y

so based on the A, B, C, D choices, D is the only one that says a correct statement

remember that like terms are numbers that have the same letters, all of them, so for example:

like terms:

5x, 11x

3ab, 18ab

and other numbers that have the same letters (can't remember the actual name right now)

non like terms:

6y, 3a

3y, 16xy

so if the letters don't match, they're not like terms

Answer 2

Answer:

D. The expression 5 y plus 2 y is equivalent to 15 y minus 8 y.

Step-by-step explanation:

15y - 8y = 7y

5y + 2y = 7y

This means that they are similar.
