Answer:
As shown in your game, you have an inequality:
2.5 x h + 10.9 > 33.4
=> 2.5 x h > 33.4 - 10.9
=> 2.5 x h > 22.5
=> h > 22.5/2.5
=> h > 9
Hope this helps!

Answer:
3
Step-by-step explanation:
3/3x + 1/x+4 = 10/7x
3/3x + 1/x+4 = 10/7x , x=0,x=-4
1/x + 1/x+4 = 10/7x
1/x + 1/x+4 - 10/7x = 0
7(x+4)+7x-10(x+4) / 7x*(x+4) = 0
7x+28+7x-10x-40 / 7x*(x+4) = 0
4x-12 / 7x*(x+4) = 0
4x-12=0
4x-=12
x=3,x=0,x=-4
x=3

N = 13/20 or 0.65
25.5n - 3 = 5.5n + 10
Add 3 to both sides of the equation.
25.5n = 5.5n + 13
Subtract 5.5n from both sides.
20n = 13
Divide both sides by 20.
n = 13/20 or 0.65
