You have to get the fractions to have a common denominator in order to add them together. what you want to do it multiply the whole number (ex. 3) by the denominator of the fraction (2/3) then add the numerator to have an improper fraction. the first trail would be 11/3 and the second trail would be 17/6. find the common denominator, add the two fractions, and then simplify the fraction the most you can.
Answer:
a + b = 16 or -16.
Step-by-step explanation:
a - b = 4
ab = 60 so a = 60/b
Substituting for a in the first equation:
60/b - b = 4
60 - b^2 = 4b
b^2 + 4b - 60 = 0
(b + 10)b - 6) = 0
b = 6, -10.
Therefore, from the first equation:
When b = -10 . a + 10 =4 giving a = -6 or
When b = 6, a - 6 = 4 giving a = 10.
So when a = -6, b = -10 and
when a = 10, b = 6.
So a + b is either 16 or -16.

Let A be asset turnover, R revenue, and S assets. You already know the equation for asset turnover:
A = R/S
Since we need to calculate revenue, we need to modify the equation a bit:
R = A*S
R = 7.2*88000
R = 633,600
This means that Ryan's net sales (revenue) were $633,600.
