A, B and C working together will finish same piece of work in 10 days
A can do a piece of work in 20 days. That is A is doing the work at a rate of 1 / 20. Therefore
B = 1 / 30
C = 1 / 60
A, B and C working togehter their rate will be added together =
A + B + C = 1 / 20 + 1 / 30 + 1 / 60 = 1 / 10
so they can work together to finish same piece of work in 10 days
The simplified version of this equation would be
-x + y
7+2=9
+3=12
+3S= 12+ 3s
+11= 23 + 3s
The quotient determined by two negative integers will be positive.
when both numbers are negative, it equals a positive. when one number is negative and the other is positive, it equals a negative.
hope this helps, God bless!
