Answer:
-4.7a-4.16
Step-by-step 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.
[tex]4\frac{1}{8} =\frac{33}{8}[/tex]
[tex]\frac{33}{8}=4.13[/tex]
-8.29+4.13= -4.16
Final answer
-4.7a-4.16
