Hey! I'll provide you the answers!
First you want to simplify the equation using cross-multiplication.

Finally, you would want to divide both sides by 15.
n = 161
First we need to make both fractions equal to each other, and that means having to have the denominators the same.
What both 3 and 12 easily go into is 12.
So we need to make both fractions have a denominator of 12, so we multiply.
2/3 * 4/4 = 8 / 12
1/4 * 3/3 = 3 / 12
Now, we know that she has 8 / 12 pounds, and she uses 3 / 12 of it, so now we subtract to find how much she has left.
8 - 3 = 5
Out of the 12 pounds of roast beef, she now has 5 / 12 left.
I think it is 17 but i am not 100% accurate
I believe the answer is C
The probability that it will land on a green face is 5/6
Therefore it is not sure that she will win but most certainly she will therefore the answer is C
Answer: 850
Step-by-step explanation:
if 250 miles takes 5 gallons then 7 gallons may give you about 850.
It looks like your just adding on 2 more.
