Answer:
The answer is B
Step-by-step explanation:
96*72=6912
One ton is $72
You have 96 tons
So you take $72 96 times

Answer:
1/12
Step-by-step explanation:
Probability is chance of occurrence.
It is observed that out of 108 trials, there were 9 successes i.e 9 times landing on the green section.
P(green) = 9/108
= 1/12
It's a simultaneous equation:
Steps:
1.Number the equations..
a+b=77 -1
a-b=13 -2
2. Choose what variable you want to use. In this case I would use the "b". Since the signs in front of the "b's" are different, add the two equations together
a + b = 77
+ + +
a (-b) = 13
Which gives;
2a = 90
Then solve to find a:
2a=90
a= 90/2
a=45
3.Then plug the "a" value into any of the original equations to find the "b" value. I would use equation 1 since the all the variables are positive.
a + b = 77
(45) + b = 77
b=77-45
b=32
4.Solution
a=45
b=32
