3500 students would actually enroll.
70% of 20000= 14000
25% of 14000= 3500
X=2y/3
x+y=30
plug in the value of x in the second equation to have one variable in the equation...
2y/3+y=30
5y/3=30
then multiply 3 on both sides...
5y=90
divide by 5 on both sides...
y=18
and to solve for x you have to plug in y on either equation...
1st way to solve for x:
x+18=30
subtract 18 on both sides...
x=12
2nd way to solve for x:
x=(18)2/3
you then solve...
x=36/3
x=12
answer: 12,18
The maximum number of bags is an illustration of the greatest common factor
The maximum number of bags John can make is 8
The given parameters are:


Start by expressing 48 and 56 as a product of their factors.


The product of the common factors between the above products is:

Multiply

The above represents the greatest common factor of 48 and 56.
Hence, the maximum number of bags John can make is 8

I think is B but I have to work this out
Answer: 1. -6. It is negative because it is less than zero. 2. 3.4. It means that it is 4/10 more than 3.
