Answer: 40
Step-by-step explanation:
1 hour and 30 min is 15 pages read
If you read for three hours its 30 pages
An hour and a half is three parts of 30 so three parts of 15 is five
But you need a whole hour so its ten
Then you add 10 and 30
Its 40 pages in 4 hours.
Answer: 3
Step-by-step explanation:
10(1/2x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = - 52
x = -52/5
Answer:
B) 4x^2y^2
Step-by-step explanation:
8x^3y^2+20x^2y^4
4(2x^3y^2+5x^2y^4)
4x^2(2xy^2+5y^4)
4x^2y^2(2x+5y^2)
So the answer is B
