Answer:
The required equation is
Step-by-step explanation:
Consider the provided information.
Let P represent the number of pages left to read after t hours.
Shryia read a 480-page-long book cover to cover in a single session, at a constant rate. After reading for 1.5 hours, she had 402 pages left to read.
Total number of page Shryia read in 1.5 hours is:
480-402 = 78
It is given that the rate is constant i.e 1.5 hours,
Therefore, she read 78 pages in 1.5 hours.
She can read page per hour
The required equation is:
Where t represents the number of hours.
It is positive 4 because you can't subtract 2-(-2)
Answer:
The value of the car in very nice condition will be $35500.
Step-by-step explanation:
Let the value of car in a very nice condition be = x
The value $62125 is or or 1.75 times of x.
Now, we can calculate for x:
x = 35500
Hence, the value of the car in very nice condition will be $35500.

The price of less expensive equipment is $1575.
Step-by-step explanation:
Let,
Price of one equipment = x
Price of other equipment = y
According to given statement;
x+y=4000 Eqn 1
x = y+850 Eqn 2
Putting Eqn 2 in Eqn 1
Dividing both sides by 2;
Putting y=1575 in Eqn 2;
The price of less expensive equipment is $1575.
