Answer:
n=-5
Step-by-step explanation:
first you have to distribute the 3 to the -6 and the 5. In return u will get -18n and 15. then you have to cancel like terms. then you have to add 18 to the 75 which gives you 93. then you divide -18 by 93 which gives you -5.166 repeating... so all you have to do is round. your final answer will be -5.

Using a proportional relationship, it is found that the two equations that have the same constant of proportionality are givn by:
с 1 and 3
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the functions and constants are given as follows:
- 3. 8y = 6x -> k = 6/8 = 3/4.
Equations 1 and 3 have the same constants, hence option c is correct.

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
