It depends on the value of x. By the way, I think you mean x^100 so I will answer based on that.
For 0<x<1, 3x > x^100
This is because x is a fraction which is less than 1. Therefore, multiplying it by itself will make an even smaller fraction whereas multiplying it by 3 (a number larger than 1) will make it a larger fraction. If you want to check this, try working it out using x = 0.1
For x>1, 3x <= x^100
This is because x is larger than 1 so it will increase when multiplied by itself. It makes sense that it should be greater than 3x in this case. Try using x = 2.
100*x/75 % or 3x/4 %
-3x+4y doesn't have a maximum value because you can plug in anything for x and anything for y. In fact, if you keep x=0 and you plug in larger and larger numbers for y, you get a larger and larger output--it's unbounded.

x=10
6/x=3/100; cross multiply 6*100 and 3*x; 600=3x; divide by three; 200=x
100 X looks larger.

If you mean 3x + 2x = 100, then x = 20. If you mean something different, you'll need to spell it out.
600/x = 3/100 3x = 60,000 x = 20,000
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
- 3x - Xsame as- 3x + (- X)= - 4X=====
(3x2 - 6x)/3x = 3x(x-2)/3x = x-2, for x<>0
3x * (x - 4) = 3x*x - 3x*4 = 3x^2 - 12x.
