Alvin's age is three times Elga's age. The sum of their ages is 116. What is Elga's age? years old

Let Elga's Age be x and Alvin's age be 3x

x + 3x = 116

4x = 116

x = 116/4

x = 29

Therefore , 3x = 3(29) = 87

Elga's Age - 29

Alvin's Age - 87

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
