If y equaled 3, then we would plug 3 into the y spot on the equation. Therefore it would be 2x+4(3)=8. Now just solve.
2x+4(3)=8
2x+12=8
2x-12=8-12
2x=-4
2x/2=-4/2
X=-2

Answer: 60 teachers</h3>
=========================================================
Explanation:
There are 500 female students and the ratio of boys to girls is 2:5
Multiply both parts of that ratio by 100 so that the "5" turns into "500"
The ratio 2:5 turns into 200:500 showing that for every 200 male students there are 500 female students. There are 200+500 = 700 students total.
Because of this 700 figure, we'll need to multiply both parts of the ratio 3:35 by 20 so that the 35 becomes 700.
The ratio 3:35 turns into 60:700. For every 60 teachers, there are 700 students.
----------------------
Another way to solve:
The ratio of boys to girls is 2:5 which we can write as 2/5
x = number of boys
2/5 = x/500
2*500 = 5x
1000 = 5x
5x = 1000
x = 1000/5
x = 200
There are 200 boys and 500 girls, so 200+500 = 700 total.
y = number of teachers
3/35 = y/700
3*700 = 35y
2100 = 35y
35y = 2100
y = 2100/35
y = 60
There are 60 teachers
The answer is A
Med range = 65+15 /2 = 40
Range = 65-15=50

Step One
Change to improper fractions.
1 3/11 = 14/11
1 3/4 = 7/4
Step Two
Find the common denominator
11 = 11 * 1
4 = 2 * 2
The common denominator = 11 * 2 * 2 = 44
Step 3
change the improper fractions to the common denominator.
-21/44 That has to be your final answer.
