Polygon abcde is dilated by a scale factor of 3 with the center of dilation at the origin to create polygon a′b′c′d′e′. if the endpoints of are b(3, 5) and c(5, 10), what is the slope of ?

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the answer is a if my teacher taught me correct

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
