Expand 8(5-r)/5=-2r as indicated: 40 - 8r
----------- = - 2r
5
Multiply both sides by 5, obtaining 40 - 8r = - 10r
Combine like terms: 40 = - 2r
Divide both sides by -2: -20 = r
The solution to 8(5-r)/5=-2r is -20. Verify this by subbing -20 for r in the given equation.
Answer:
x−2/x+3
Step-by-step explanation:
(x−3)(x−2)/(x+3)(x−3)
so (x−3) will be cancelled from both denominator and nominator
(x−2)/(x+3)
Answer:
A. They make the same amount
Step-by-step explanation:
You can use the cross multiplication method to find the answer:
$ hrs
200 × 10
300 15
200 × 15 = 3000
300 × 10 = 3000
So 9 x 8 = 72
72/2 = 36
36 x 10 = 360
so 360in
