Question

Which of the following terms can be combined in this expression?

13 minus x over 5 + 6.2 y + 20.5 x minus 3 over 8 y

Negative 13 can be combined with 20.5.

6.2 y can be combined with 20.5 x.

6.2 y can be combined with Negative 3 over 8 y.

Negative x over 5 can be combined with Negative 3 over 8 y.

Answer 1

Given:

Consider the expression is:

`13-(x)/(5)+6.2y+20.5x-(3)/(8)y`

To find:

The like terms that can be combined in this expression.

Solution:

Two terms are called like terms, if they have same variables of same degree.

We have,

`13-(x)/(5)+6.2y+20.5x-(3)/(8)y`

In the given expression, the pairs of likes terms are:

Pair 1:
`-(x)/(5)` and
`20.5x`

Pair 2:
`6.2y` and
`-(3)/(8)y`

It means
`-(x)/(5)` can be combined with
`20.5x` and
`6.2y` can be combined with
`-(3)/(8)y`.

Therefore, the correct option is C.
