Answer:
Help with what? I don't see anything else :(
Step-by-step explanation:
Male to female is 8:5
So
Let's make male = 8x
female = 5x
8x-400/5x-300=8/3
The 8/3 is because that is what the ratio was after some of the students left
multiply by 5x-300 on both sides
8x-400=(5x-300)*(8/3)
multiply by 3 on both sides to remove the denominator
(8x-400)*3=(5x-300)*8
24x-1200=40x-2400
+2400 +2400
24x+1200=40x
-24x -24x
1200=16x
divide by 16
1200/16=16x/16
75=x
Now to find total we do 8x+5x we said male were 8x and female were 5x
8(75)+5(75)
600+375=975 total students
The attached image represents the interval 2 < x ≤ 9 on the number line
<h3>How to highlight the interval?</h3>
The interval is given as:
2 < x ≤ 9
The above interval means that:
- 2 is exclusive of the values of x (because of the < inequality symbol)
- 9 is inclusive of the values of x (because of the ≤ inequality symbol)
In inequality, the < symbol uses an open circle, while the ≤ uses a closed circle
Next, we highlight the interval using the above rules (see attachment)
