8.9 because you divide and multiply or u can just plug and chug
Answer:
a * c^2 = b
Step-by-step explanation:
you would want to multiply both sides of the equation by c^2
a * c^2 = b
That gets you this formula you can then plug your numbers in
You would write the equation like this:
24-10n=64+8n
40 and 60
40 = 20 x 2
60 = 20 x 3
GCF = 20

Answer:
12t -3 = 18t
Step-by-step explanation:
Let
d = your friends distance in miles
t = time in hrs
Your equation:
d - 3 = 18t (1)
Because you are 3 miles behind your friend
Your Friend's equation:
d = 12t (2)
To find the amount of time t it takes for you to catch up with your friend,
Substitute (2) into (1)
d - 3 = 18t
12t - 3 = 18t
Equation to find the amount of time t it takes for you to catch up to your friend is 12t - 3 = 18t
Solving the equation
12t - 3 = 18t
Collect like terms
12t - 18t = 3
-6t = 3
t = 3/-6
= -0.5
t = 1/2 hour
Time can not be negative, therefore it will take 1/2 an hour to catch up with your friend
