Step-by-step explanation:
_______________________________________________
Let "J" represent the number of times julia has read the book.
Let "K" represent the number of times Kami has read the book.
J = 6 ;
J = 3K ;
Solve for "K" ;
J = 6 = 3K ;
→ 6 = 3K ;
↔ 3K = 6 ;
Divide each side of the equation by "3" ;
to isolate "K" on one side of the equation; & to solve for "K" :
→ 3K / 3 = 6 / 3 ;
to get:
K = 2 .

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:
Remember rise over run for the slope.
the slope is always the number on the left side (x) and the y intercept is the number in the right (y)
(x,y).
Answer:
x = -8
Step-by-step explanation:
1/4x +2= -5/8x - 5
Add 5/8x to each side
1/4x +5/8x +2= -5/8x+5/8x - 5
1/4x+5/8x +2= - 5
Subtract 2 from each side
1/4x+5/8x +2-2= - 5-2
1/4x+5/8x = - 7
Get a common denominator
1/4 *2/2 x + 5/8x = -7
2/8x + 5/8x = -7
7/8x = -7
Multiply each side by 8/7
8/7x * 7/8x = -7 *8/7
x = -8
