Question

9.1(6)+8.7(7)=_+60.9
How do I solve this?

Answer 1

The answer is 54.6.

9.1(6)+8.7(7)=54.6+60.9

Explanation:

Given:

9.1(6)+8.7(7)=_+60.9

Now, to solve it:

9.1(6)+8.7(7)=_+60.9

Let the _be x.

So, we remove parenthesis first that makes it multiply with the number next to it:

`9.1* 6+8.7* 7=x+60.9`

`54.6+60.9=x+60.9`

Now adding on L.H.S:

`115.5=x+60.9`

Subtracting on both sides by 60.9 we get:

`54.6=x`

`x=54.6`

Therefore, the answer is 54.6.
