Answer:
60 is your answer.
Step-by-step explanation:
x - 8 = 10
add 8 to both sides,
x = 18
substitute 18 for x in the second equation:
4(18) - 12 = 72 - 12 = 60

Hello!
The time difference between checkpoint 1 and checkpoint 2 is an hour and a half.
At checkpoint A, the total amount of miles driven is 120. At checkpoint B, the total amount of miles driven is 195.
To find the amount of miles driven between checkpoint 1 and 2, you will subtract the amount of miles at checkpoint 1 from checkpoint 2:
195-120= 75
The car drove 75 miles between 1:00pm to 2:30 pm. Because the total time between the checkpoints was an hour and a half, we can divide it by three (90 minutes total). We also need to divide the number of miles (75) by three to find an accurate answer.
90/3=30
75/3=25
The car drove 25 minutes in half an hour. Now, one hour consists of 60 minutes, so we will multiply both calculations by 2 (for the total hour and the total amount of miles driven in the hour):
30x2=60
25x2=50
The car drove 50 miles per hour between checkpoints A and B.
I hope this helps you! Have a great day!
I should think that this works just like the trapezoids
volume=base times height
so
base=pir^2
height=x
r=d/2=14/2=7
base=pi7^2=49pi
so
V=49pix
1176pi=49pix
divide both sides by 49pi
24=x
I would say 24 units

Where is the graph Buddy?????
The first one is A and the second one is D.
