Answer:
The answer is 54.6.
9.1(6)+8.7(7)=54.6+60.9
Step-by-step 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:
[tex]9.1\times 6+8.7\times 7=x+60.9[/tex]
[tex]54.6+60.9=x+60.9[/tex]
Now adding on L.H.S:
[tex]115.5=x+60.9[/tex]
Subtracting on both sides by 60.9 we get:
[tex]54.6=x[/tex]
[tex]x=54.6[/tex]
Therefore, the answer is 54.6.
