Answer:
1/2 now substitute 45 degrees
Step-by-step explanation:
30kx - 6kx = 8
24kx = 8 /(÷8)
3kx = 1
x = 1/3k
If alonzo is x then the equation is
x + (x +3) + 2(x + 3) = 57
Which equals
x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12
This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old
Answer = 15 years old
