Alright, so he went the same distance there and back, but at different speeds

hmm

d=st
d/s=t

total time is 9.5hr

alright

so distance there=distance back we will call both of them d

so

speed there is 10
speed back is 9
total time is 9.5

so
d/sthere+d/sback=totaltime
d/10+d/9=9.5
times both sides by 90
9d+10d=855
19d=855
divide both sides by 19
d=45

he can ride 45mi away

You know that 12x=60, and that x=5. Which property of equality would you use to conclude that 12•5=60?
alexandr402 [8]

ANSWER

The substitution property of equality.

EXPLANATION

We know that:

12x = 60

and that

x = 5

Since x=5 or 5=x , we can substitute x for 5 wherever we see x in the given equation.

When we do that, we obtain;

12 \bullet \: 5 = 60

This is what we refer to as the substitution property of equality.
