The ratio of the diameters of two circles is 3:5. The circumference of the larger circle is approximately 113.1 m. What is the approximate circumference of the smaller circle?7.5 m

22.6 m

67.9 m

188.5 m

Answers

Answer 1
Answer: Given:
diameter of two circles  3:5
small circle : 3
large circle : 5

circumference of two circles x : 113.1
small circle : ? 
large circle : 113.1 m

3:5 = x :113.1
3*113.1 = 5*x
339.3 = 5x
339.3 / 5 = x
67.86 = x

The approximate circumference of the smaller circle is 67.9 m.

Answer: No Solution

Step-by-step explanation:

When there are absolute values on both sides, you simply just get rid off the signs. (Normally, it results in positive and negative on the other side)

SOLVE:

Given

|-9-7x|=|23-7x|

No absolute value sign

-9-7x=23-7x

Add 7x on both sides

-9=23

ANSWER:

This is no solution, because -9≠23
