Answer: 8s
Step-by-step explanation:
There are 3 terms to : 5s + 13s - 10s
They are all like terms because each of the numbers(coefficients) have the same exact variables behind it. Because they are like terms you can combine to be 1 term
add the coefficients:
5s + 13s - 10s
18s -10s
8s
So answer is 8s
