56 pages/4 hours = 126 pages/x pages
Then you cross multiply
56*x =4*126 ---> 56x=504
Then you divide 56 to both sides
56x/56=504/56
The 56 cancels on the left side and then you get
x=9
So your proportion are:
56 pages/4hours=126 pages/9 hours
Step-by-step explanation:
2x + 10y = 50 ... 1
1.5x + 25y = 90 ...2
...1 × 2.5
5x + 25y = 125 ...3
...3 - ...2
3.5x = 35
x = 10
replaced x = 10 in ...1
2(10) + 10y = 50
20 + 10y = 50
10y = 50 - 20
10y = 30
y = 3
Answer: 3p = 1/2
