then;
our equation becomes:
therefore, the expression which replace the box to form an equation is
I'm pretty sure your answer should be approximately 10.2 because if its asking what "x" is closest to, then 10.2 would be the number it is closest to on the number line. Hope this helps you ^-^

Answer:
The answer to your question is 2 hours
Step-by-step explanation:
Data
Juan speed = 4 mi/h
Cathy speed = 7 mi/h
t = x
Formula
speed = distance/time
Solve for distance
distance = speed x time
d = s x t
Distance travelled by Juan
d = 4t
Distance travelled by Juan in 1.5 h
d = 4(1.5)
d = 6 mi
total distance d = 6 + 4t
Distance travelled by Cathy
d = vt
d = 7t
Equal both equations
6 + 4t = 7t
Solve for t
6 = 7t - 4t
6 = 3t
6/3 = t
2 = t
Cathy wll catch up with Juan in 2 hours
