Answer:
4
Step-by-step explanation:
Assign x for the number. Write an equation.
2x = 6+.5x (I'm guessing you means "6 more than half that number")
1.5x = 6 -->
x = 4
Here's another one.
See the attached picture.
$38x0.15= 5.70
$38.00+$5.70=$43.70 is the total bill
there are 60 minutes per hour
24/60 = 0.4 miles per minute
0.4*5 = 2
they will ride 2 miles in 5 minutes
