Emma took a taxi from the airport to her house.
She paid a flat fee of $5 plus $3.70 per mile.
The fare came to $42.

For Emma's taxi ride, which equation gives the correct distance (d) in miles

I think it’s 6 miles I’m not sure actually

5 + 3.70d = 42

Subtract 5 from both sides.
5 + 3.70 = 42
-5 -5

3.70d = 37

Divide both sides by 3.70
3.70d = 37
___
3.70 3.70

d= 10

Check: substitute 10 for d

5 + 3.70(10) = 42 ??
5 + 37 = 42 ??

42 = 42 :)
