Answer:

Step-by-step explanation:
The correct question is
Naoya read a book cover to cover in a single session, at a rate of 55 pages per hour. After 4 hours, he had 350 pages left to read.
Let y represent the number of pages left to read after x hours.
Complete the equation for the relationship between the number of pages left and number of hours.
Let
x -----> the time in hours
y ----> the number of pages left to read
we know that
The linear equation in point-slope form is equal to

In this problem we have
----> is negative because the linear function is decreasing

substitute




Answer:
It would equal 8X
Step-by-step explanation:
Think of it as 7X+1X
7+1=8
so therefore:
7X+1X=8X
For the answer to the question above, \
Let
D = Dominic weight
R = Ralph weight
P = Peter weight
We have three unknowns so we should set up three equations. We do as follows:
D = 0.5R
P = 3D
D+R+P = 720
Solving simultaneously we obtain,
D = 120
R = 240
P = 360
<span>So the answer is 120 is the weight of Dominic</span>
