Answer:
hi the answer to your question should be 50 miles
Step-by-step explanation:
hope this helps have a great day!
X = measure of each of the legs
"perimeter is 8 more than 2 times one of the legs" ---> P = 2x+8
P = 28 is the given perimeter
So,
P = 2x+8
28 = 2x+8
2x+8 = 28
2x = 20
x = 10
If x = 10, then the two legs add up to x+x = 10+10 = 20
Leaving P-20 = 28-20 = 8 inches left over for the base
You have the correct answer (choice D, 8 inches) though your steps are a bit confusing at some parts. Such as the part where you wrote 2x = 10 twice. I think I know what you were trying to say.
88+x≥92
Subtract 88 from each side to get:x≥4
So now you add 4 to the 92 to get 96, Mindy's minimum score on her second test to get at least a 92 average.
