Step-by-step explanation: No the right answer? Let me know!
23 inches
x = Mindy's height
2x - 20 = 66
- 20 -20
2x = 46
/2 /2
x = 23
Answer:
13x^2+2x+5
Step-by-step explanation:
that is the right answer
You have to combine the like terms.
Distance = rate*time
convert minutes to hour first because the question talking about 15 mile per hour
40 mins = 40/60 2/3 hrs
30 mins = 30/60 = 1/2hrs
Assume that s be the speed when Fritz driving, so
s + 15 will be the speed of the train.
We know the time we know the speed, Next
distance that Fritz drive =

distance the train travel =

The question: Assume that the train travels the same distance as the car

Now we know that Fritz drive at 45 mph,
distance =
