Step-by-step explanation:
move 7 times to the right to check answer 1.<u>5000000</u>
4x+y=10
y=10-4x
----------
Now y=f(x), so:
f(x)=10-4x
K = kims age, s = her sisters age
k = 2s
k + s = 36
2s + s = 36 <== ur equation
3s = 36
s = 36/3
s = 12 <== the sister is 12
k = 2s
k = 2(12)
k = 24 <== Kim is 24
The average is approximately 3 inches an hour
