Juan is learning about like terms in his math class. He must check all the combinations below that are like terms. Which ones should he check? 3x and x
One-fourth and 0.5
–m and 8m
–xy2 and 2xy2
y and y2
4xy and –5x2y
m and n
–7 and 6

3x and x

One-fourth and 0.5

–m and 8m

–xy2 and 2xy2

–7 and 6

Step-by-step explanation:

I took the edge 2020 assignment

3x and x

One-fourth and 0.5

–m and 8m

–xy^2 and 2xy^2

-7 and 6

Step-by-step explanation:

Terms whose variables (such as x or y) with any exponents (such as the 2 in x2) are the same.

Examples:

7x and 2x are like terms because they are both "x".

3x2 and −2x2 are like terms because they are both "x2".

But 7x and 7x2 are NOT like terms (the exponents are different), they are unlike terms.

Like terms can be added together.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
