Answer:
9 hours
Step-by-step explanation:
Since the group of men remains the same, number of hours is proportional to number of radios.
1300/26 = 450/h
h = 26 * 450 / 1300 = 9 hours
I don't think its possible to do this... you have to have 2 equations
Answer:
The numbers are 23 and 7
Step-by-step explanation:
1. Set up the equations
Let x = the greater number
and y = the smaller number. Then
(1) x - y = 16
4y = 4 times the smaller number and
4y - 5 = 5 less than 4 times the smaller number. Then
(2) x = 4y - 5
You have a system of two equations:

2. Solve the equations

The larger number is 23; the smaller number is 7.
3. Check

OK.
Answer: 38
Step-by-step explanation:
7/2 = 63/g..7 red apples to 2 green apples = 63 red apples to g green apples
cross multiply
(7)(g) = (2)(63)
7g = 126
g = 126/7
g = 18
so they sold 63 red apples and 18 green apples...for a total of (63 + 18) = 81 apples sold
