It is 2500 use a calculator
Let
x = time of Byran's work
x + 10 = time of Andy's work
Rate is usually expressed a reciprocal. The total rate will be 12 minutes.
1/x + 1/(x + 10) = 1/12
The value of x will be 20 minutes.
Therefore Byran can take 20 minutes while Andy can take 30 minutes.

A. she has 29 complete out of 100 and we want to find how many more so

x=71
E) 2sin0 is the answer ^.^
