Step-by-step explanation:
First get x on its own:
Subtract 3 from each side
y - 3 = 2x
Divide through by 2
y/2 - 3/2 = x
or x = y/2 - 3/2
Now simply switch labels: x↔y
y = x/2 - 3/2
if the girls are "g" and the boys are "b"
g + b = 13
b = g + 7 <--- 7 more boys than girls
1. <u>Correct</u>
2. <u>Incorrect</u>, answer is x ≤ -4.25 This is because the line goes to the left so it is less than or equal to.
3. <u>Incorrect</u>, the answer is the choice at the top, because it is greater than, it goes to the right and has a empty circle.
4. <u>Incorrect</u>, the answer is the choice at the bottom cuz it is greater than or equal to so the line goes to the right and the circle is filled in.
Hope that helps u!!
