So I took the test and my teacher said to label all of the degrees so
angle 1,3,5,7,9,11,13,15 all = 95 degrees
angle 2,4,6,8,10,12,14,16 all = 85 degrees
I know 1 and 3 are vertical angles
3 and 8 are same side interior angle
4 and 14 alternate interior angles
6 and 12 are alternate exterior angles
13 and 9 are corresponding angles
4 and 7 are same side interior angles
I believe these are correct but you might want to double check with some other source
The first one is 18.5. That was a result of dividing decimals.
Second one is $4.82 because you are trying to find the unit rate.
Third is 2608.75 dollars earned. You multiply the number of memberships with cost, 152. Now you add that with the monthly earnings, resulting in that answer.
(2x-4)(x+5) expand with indicated multiplication
2x^2+10x-4x-20
2x^2+6x-20
7y^2 - y^2 = 6y^2
hope it helps
