Answer:
This is really hard
Step-by-step explanation:
This ratio means that there are two men for every three women. So, the ratio of women to men is 3:2.
The total amount of students includes both men and women, so you would use 5. The ratio of women to total student is 3:5.
To find the percent, you divide the first number by the second number and multiply by 100. Our first number is the men, which is 2, and the total students are the second number, or 5.
2/5 = .4 * 100 = 40%
A ratio is the same thing as a fraction, so you take the amount of women (3) and put that over the total student body (5). 3/5 is your fraction.
Good luck, and I hope I helped!
Answer:
16.5
Step-by-step explanation:
Just put in the values of C and y first into the expression.
C = 4x + 5y
Put in values.
51 = 4x + 5(-3)
Evaluate.
51 = 4x + (-15)
Swap positions.
4x + (-15) = 51
Shift (-15) to the other side and change to (+15).
4x = 51 + 15
= 66
Find x.
x = 66 ÷ 4
x = 16.5
