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
Answer:
44=y
Step-by-step explanation:
27+x=y
We know x = 17, so we can substitute x=17 into the equation
27 + 17 = y
44=y
Answer:
$7.5
Step-by-step explanation:
1 quart = 4 cups
So:
12 cups = 12/4 = 3 quarts
Each quart is 2.5 dollars
3 * 2.5 = $7.5
D. Because you're multiplying 3 by a number which is what the variable represents (n), then you're just adding 7 to that which equals 19 all together. It all translates to 3n+7=19.
It creates a 90 degree angle so that means its perpendicular.
