Answer: n + (n + 2) = 84

Answer:
yes
Step-by-step explanation:
2x-4=6
Let x = 5
2*5 - 4 = 6
10 -4 =6
6 = 6
Since this is true, x=5 is a solution to the equation
The money altogether is 8.00$
So there are x girls and x-4 boys and together they make 28:
x+x-4=28
2x-4=28
2x=32
x=16
so there are 16 girls and 12 boys.
the ratio is then 16:12, or we can simplify (by dividing both sides by 4): 4:3
so the best answer is 4:3.
