Membership to a music club cost $40. members pay $20 per music lesson and non members pay $25 per music lesson. how many music lessons would have to be taken for the cost to be the same for members and non members?

isnt it 100?

20x5=100

25x4=100

same price?

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
