So here is the answer. Initially, Ed's toy cars compared to Pete's toy cars was 5:2. So for every 5 cars that Ed has, Pete has 2. Now that Ed gave 30 cars to Pete. So here it goes. The total number of ratio units is 5+2=7, so each will have an equal number if they both have 3.5 ratio units. That is, if Ed transfers to Pete 1.5 ratio units, their car counts will be equal. Thus 1.5 ratio units = 30 cars, or 1 ratio unit = 20 cars. Therefore, this makes <span> 7*20 cars = 140 cars.

Step-by-step explanation:
For the equation 
use the substitution 
Then the equation will take look
Solve this quadratic equation:
Thus,
Answer:
=−3x+42
Step-by-step explanation:
Let's simplify step-by-step.
−4(x−7)+x+14
Distribute:
=(−4)(x)+(−4)(−7)+x+14
=−4x+28+x+14
Combine Like Terms:
=−4x+28+x+14
=(−4x+x)+(28+14)
=−3x+42
So,
The range will simply be the absolute value of the difference between the highest and lowest price.
The highest price is $2285.
The lowest price is $1116.
The absolute value of the difference between these two prices is:
|2285 - 1116| = 1169
The range of the prices for the gold phone is $1169.
