Answer:
The answer is <u>54.6</u>.
9.1(6)+8.7(7)=<u>54.6</u>+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:
Now adding on L.H.S:
Subtracting on both sides by 60.9 we get:
Therefore, the answer is 54.6.
The number of handshakes is the number of ways 6 objects can be selected 2 at a time.
.. C(6,2) = 6·5/(2·1) = 15
The appropriate choice is
... C) 15
_____
Consider that each person can shake hands with 5 others. That's a total of 6*5 = 30 handshakes, but it counts both A shaking with B and B shaking with A. If each pair of persons only shakes hands once, the number of handshakes is 30/2 = 15.
Answer:
1. is 0.9 or 9/10. 2. is 43/36 or 1.19
The top one can go by halves, and the bottom one can go by 1's. so for the top 1/2, 1, 1 1/2, 2, and 2 1/2 while the bottom would be 0 1 2 3 4... and so on
