A good way of doing this problem would be to use cross multiplication of ratios
<u />
Then cross multiply
(10 girls)(270 students)=(X girls)(18 students)
2700=18x
150=x
3 times (2x + 5) is 6x + 15.
6x + 15 = 9 + 3x.
Group by like terms. 6 = -3x
Divide to get x by itself. 6/-3 = -2
Thus -2 = x
Answer: simplifying expression
Step-by-step explanation:
A is 82
a = 42.69
c= 43.11

So, to find the day rate, we divide 90 by 6 = 15
So then we find 15n = 300 for the rate.
n = 20
It will take Stephen 20 days to read a 300-page book
