Answer:
you have the answer correct actually
Step-by-step explanation:
Answer: 12 students
Step-by-step explanation:
Let X and Y stand for the number of students in each respective class.
We know:
X/Y = 2/5, and
Y = X+24
We want to find the number of students, x, that when transferred from Y to X, will make the classes equal in size. We can express this as:
(Y-x)/(X+x) = 1
---
We can rearrange X/Y = 2/5 to:
X = 2Y/5
The use this value of X in the second equation:
Y = X+24
Y =2Y/5+24
5Y = 2Y + 120
3Y = 120
Y = 40
Since Y = X+24
40 = X + 24
X = 16
--
Now we want x, the number of students transferring from Class Y to Class X, to be a value such that X = Y:
(Y-x)=(X+x)
(40-x)=(16+x)
24 = 2x
x = 12
12 students must transfer to the more difficult, very early morning, class.
Answer:
The cost of 16 ounce bottle would be .15 cents per ounce = $2.40
Step-by-step explanation:
2.40/16= .15
2.80/28= .10
This would be the equation:
Y= 5/2x+5
I hope I've helped!
They definitely can be positive they can be negative and they can have an absolute value but I would choose they both can be positive and negative
