Answer:
4 pages per hour
Step-by-step explanation:
Willie and Pedro are reading the same book. Willie read 108 pages in 3 hours, and Pedro read 160 pages in 5 hours.
We find how many pages per hour each of them read.
For Willie
Willie read 108 pages in 3 hours,
3 hours = 108 pages
1 hour = x
Cross Multiply
3x = 108 pages × 1 hours
x = 108 pages/3
x = 36 pages per hour
For Pedro
Pedro read 160 pages in 5 hours
5 hours = 160 pages
1 hour = x
Cross Multiply
5x = 160 pages × 1 hours
x = 160 pages/5
x = 32 pages per hour.
How many more pages per hour did Willie read?
This is calculated as:
36 pages/hour - 32 pages per hour
= 4 pages per hour

Answer:
6x^2·y^6·√(2x)
Step-by-step explanation:
As in the answer above, parentheses are useful for identifying what is under the radical and what is not.
Answer:
6
Step-by-step explanation:
find the gradient of the line using the y=mx +c method rearrange 2x+12y=-1 to become 12y=-2x-1...divide both sides by 12 so m=-1/6. To find the slope of a line perpendicular to 2x+12y=-1 when their slopes multiply they give -1. The gradient of the perpendicular line is 6. Using the point it passed through (0,9) use the equation of a line formula which would be y-9/x-0=6
cross multiply and you'll get y=6x+9
