Question

Combine like terms to create an equivalent expression -3.6-1.9t+1.2+5.1t​

Answer 1

Answer:

-2.4 + 3.2t

Step-by-step explanation:

To combine the like terms, add both the numbers with the variable t together and the others without together.

-3.6+1.2= -2.4

-1.9t + 5.1t = 3.2t

Putting the sums together you should get:

-2.4 + 3.2t

If you're confused about how to subtract/add negative numbers, I like to ignore the sign--depending on what it is of course. For example, I rewrite -3.6+1.2 as 3.6-1.2. When you get the answer for that (2.4), add a negative symbol in front because the negative number was greater than the positive. I hope that helps rather than confusing you.
