5x2 * tx + -6x * 4x2 = -54 x^3
5t - 24 = -54
5t = -30
t =-6
a = k b/c sub in values given to calc k the proportionality constant
then use it in the subsequent proprtions..... but it appears your question is missing some info or typed incorrectly....
B + B + 120 = 192
2 B = 72
B = 36 tons A = 192-36=156 tons
I believe it was originally an incorrect answer....see this original post NOW.....
I do not believe this is correct....see below:
So....you are obviously just looking for 'answers' and not really caring about learning HOW the answer was found (you've not asked for any follow up....) :
b.) 5 C 2 = 10
c.) 9 C 2 = 36
d.) 14 C 2= 91
Goats are 2 out of (3+2= 5) or 2/5ths of the animals cows are 3/5
2/5x + 210 = 3/5 x
210 = 1/5 x
x = 5* 210 = 1050 animals

Well...... you cannot have a denominator = 0
so x cannot equal -8 all other REAL values of x will result in non-zero denominators
domain = (-∞,-8) U (-8,+∞)
