Answer:
First: 44
Second:
a: 2.5
b: 37.5
Step-by-step explanation:
For the first question it shows how many pages she can read in twenty minutes. The ratio is 20-5.
First we're going to divide, 20/5=4, it takes her 4 minutes to read 1 page.
Remember every five pages it takes her 20 minutes and there are two 5 in the number 11, so that's 40. Just one more page left, above we figured out how many minutes it takes her to read one page which is 4. 40+4=44.
Now onto the second question.
a: all we do is 10/4= 2.5
To check this we can add 2.5 4 times (or 2.5x4) and we would get 10.
B: Since we already know from the question above that you need 2.5 ounces of cheese for each pizza all we'll do is 2.5x15= 37.5
I hope this helps you and isn't confusing!
This answer is vague in whether they want you to add just the length and the width or if they are asking that the perimeter is 96 yards. I will show both.
The length is width - 12. Lets call width x.
Length = x - 12
Width = x
So if it is just the sum of the length and width, it would be x + x -12 = 96
2 x - 12 = 96
2 x = 108
x = 54
Length would be 54 - 12 = 42 yards.
If it was perimeter, the values would be the same except 2(x) + 2(x-12) = 96
2x + 2x -24 = 96
4x = 120
x = 30
Length = 30 - 12 = 18 yards
I hope this helps :-)
