40+20=60
90-60=30
30 divided by 60=0.3333
33.33% makes up the last classroom
16 3/8 I so sorry if wrong glade I could help
Answer:
x = -11/9
Step-by-step explanation:
3(x-4) + 1 = 12x
Step 1: Use distributive property
3*x - 3*4 + 1 = 12x
3x - 12 + 1 = 12x
Step 2: Combine like terms
3x - 11 = 12x
Step 3: Subtract '3x' from both sides
-11 = 12x - 3x
-11 = 9x
Step 4: Divide both sides by 9
-11/9 = x
I think that Neil has 12, Otto has 3 and Peter has 10.
F(x)=2x^2-x-6
Factoring:
f(x)=2(2x^2-x-6)/2=(2^2x^2-2x-12)/2=[(2x)^2-(2x)-12]/2
f(x)=(2x-4)(2x+3)/2=(2x/2-4/2)(2x+3)→f(x)=(x-2)(2x+3)
g(x)=x^2-4
Factoring
g(x)=[sqrt(x^2)-sqrt(4)][sqrt(x^2)+sqrt(4)]
g(x)=(x-2)(x+2)
f(x)/g(x)=[(x-2)(2x+3)] / [(x-2)(x+2)
Simplifying:
f(x)/g(x)=(2x+3)/(x+2)
Answer: Third Option (2x+3)/(x+2)
