x-4=x(2)
x-4=2x
+4 +4
8 = 6
lilly has 8 stamps and mackenzie has 6
You wanna
divide 85 and 52
because he can run 20 KM in 85 min
and he wants to see how long it takes him to run 52 KM
So the first one is correct
Hey there,
So let's start off with one part of this equation
. . . 
would be 0.01.
So, we have 0.01 has our answer (so far).
Then we would do 7.1 × 0.01, this would give us
. . .
0.071.Your correct and final answer would be

Hope this helps you!
