C) 8 is the appropriate choice
4 dozen are made from 3 cups of flour, so twice that flour (6 cups) will produce twice the number of cookies, 8 dozen.
325 three hundred twenty-five
Answer:
Step-by-step explanation:
"The difference of two numbers is 15."
x-y = 15
x>y
"Five times the smaller number is the same as 9 less than twice the larger number."
5y = 2x-9
y = x-15
substitution
5(x-15) = 2x-9
5x-75 = 2x-9
3x = 66
x = 22
y = x-15 = 7
5+7=12 is the number of elements.
16,200/12=1350 value of each element.
5+1350=6,750 males.
7*1,350=9,450 females.
Proofs:
6,750+9,450=16,200
5/7=6,750/9,450
5*9,450=7*6,750

For this question, we can divide both numbers by 8, as they are both divisible by 8. Then, we will be left with our answer, which will be a 3 degree drop every hour.
