Mel is 5 years older than rafie and anna is twice as old as rafie. the sum of their age is 57. how old is mel?

Mel is 18.

Step-by-step explanation:

57 = x + (5 + x) + (2x)

57 = x + 5 + x + 2x

57 = (x + x + 2x) + (5)

57 = 4x + 5

57 - 5 = 4x + 5 - 5

52 / 4 = 4x / 4

13 = x

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
