The distance between A and B and the distance between C and D are the same ( the 2 little lines indicate that).

This means the two arc lengths would also be the same.

Set the equations equal to each other,, solve for x then solve for the arc length.

AB = 3x +9  

CD = 11x-71

3x+9 = 11x-71

Subtract 3x from both sides:

9 = 8x-71

Add 71 to both sides:

80 = 8x

Divide both sides by 8:

x = 10

Now solve for AB:

3x +9 = 3(10) +9 = 30+9 = 39

The answer is AB = 39

Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of b
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
