12. Consider the following equation a + 0.072 = 1.07a
Which statement explains how the quantities are related?
a. Increasing by 7% is the same as multiplying by 1.07
Increasing by 7% is the same as multiplying by 0.07
The quantities are not related
d. Not enough information

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
