Answer:
E) b^2
Step-by-step explanation:
Solving the first equation for a, we get ...
a - b = 0
a = b . . . . . . add b to both sides
Now, the expression ab can be rewritten as
ab = bb = b^2 . . . . . . substitute b for a
Answer:

or in decimal form

Step-by-step explanation:
The midpoint of the line with endpoints
and
is
. just take the average between the points
so given the points (1,0) and (2,-10)




the midpoint is found as follows:




or in decimal form

I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
