Answer:
33 miles
Step-by-step explanation:
5.5÷4= 1.375 gal per round
1.375×24= 33 miles
Answer:
3
Step-by-step explanation: So first you have to make this word problem into a equation into standard form so 20 is our (y) because that is the additional charge but our slope is 3 because that is what they charge per hr **when they say (per) usually the member with it is the slope** (sry I’m not the best explainer)
12x = 12; x = 1
That simple
So to solve this you need to reverse factor this problem
x^2 + 8x + 7 = 0
The common formula is this for factoring ax^2 + bx + c
Now you have to think what multplties to "c" and adds up to "b".
So in this case it's 7 x 1 = 7 and 7 + 1 = 8
So you set it up like this
(x + 7)(x + 1) = 0
So now you can check the factors by multiplying them together and see if it gets your original equation which is does.
So finally to get the answers you need to set each parenthesis to 0 and solve for x.
x + 7 = 0
x + 1 = 0
and we get x = -1 and - 7
You can also plug these two answers back into your original equation to see if it equals 0.

So if she still has $27.12, then during her call, she used a total of $2.88.
$2.88 = 288 cents.
Therefore 288 divided by 6 = 48
Therefore the answer is 48 minutes.
