Neporo4naja [7]

Answer:

x+(3x+2)=30

Step-by-step explanation:

Let

x ----> the length of Zach's car

y ----> the length of Ginny's car

we know that

The sum of the lengths of both cars is 30 inches

so

x+y=30 ----> equation A

Ginny's car is 2 more than 3 times the length of Zach's car

so

y=3x+2 ----> equation B

substitute equation B in equation A

x+(3x+2)=30

A radio station requires DJs to play 2 commercials for every 10 songs they play.What is the unit rate of songs to commercial?
slavikrds [6]
The correct answer for this question is that the unit rate is 5:1. We can work this out by simplifying down the 2 commercials to every 10 songs ration, so that 10:2 becomes 5:1. We can work this out by halving the original ratio to simplify it.

Area of the frame surrounding the mirror = (196 - 4pi)x2 = 183.43x2
