In seven years her mother will be 38 +7 = 45 years old.
She will be 5 times as old, so divide 45 by 5: 45/5 = 9. Elaine will be 9 years old then, so she is 9-7 = 2 years old now.
The answer is :
y = 2x - 4

Answer:
Step-by-step explanation:
hello :
100^m / 1000^n
look : 100 = 10² and 1000 = 10^3
so : 100^m = (10²)^m= 10^2m and 1000^n = ( 10^3)^n = 10^3n
100^m / 1000^n = 10^2m / 10^3n
conclusion : 100^m / 1000^n = (10^(2m-3n)) when : z = 2m-3n
