Question

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

Answer 1

Answer:

Option (3) is correct .

We can combine 6.2y with $-\frac{3}{8}y$  

Step-by-step explanation:

      Consider the given expression $-13-\frac{x}{5}+6.2y+20.5x-\frac{3}{8}y$  

We have to find the two terms can be combined in this expression.

We can combine those term which have same variable with same degree.

Here, since degree of each variable is 1 and contain two variables x and y.

So we can combine x terms together and y terms together as ,

$-13-\frac{x}{5}+6.2y+20.5x-\frac{3}{8}y=-13+(-\frac{1}{5}+20.5)x+(6.2-\frac{3}{8})y$  

Thus, option (3) is correct .

We can combine 6.2y with $-\frac{3}{8}y$
