Question

Combine the like terms:
7.6a - 8.29 - 12.3a + 4 1/8

Answer 1

-4.7a-4.16

Explanation:

Combine like terms, are to combine the numbers or variables together, to make the expression simplified.

In 7.6a - 8.29 - 12.3a + 4 1/8 you can make it smaller, so that is what you will do.

Start with 7.6a. Find another that has a "a" in the end.

7.6a and -12.3a can go together.

7.6a-12.3a=-4.7a

Now, there are 2 terms left that can go together.

-8.29 and 4 1/8.

Make 4 1/8 into a decimal.

`4(1)/(8) =(33)/(8)`

`(33)/(8)=4.13`

-8.29+4.13= -4.16

Final answer

-4.7a-4.16
