Answer: Option A

Step-by-step explanation:
In a probabilistic experiment, when two events A and B are dependent on each other, then the probability of occurrence A since B occurs is:

Then if
and
then:

C. monomial because xy is only one number and not two.
Method One
You could divide by 5 right away.
20/5 = - 3 + x
4 = - 3 + x Add 3 to both sides.
4 + 3 = x
x = 7
Method Two.
You could remove the brackets. This is slightly longer, but some questions can only be solved that way.
20 = 5(-3) + 5x
20 = -15 + 5x Add 15 to both sides
20 + 15 = 5x
35 = 5x Divide by 5
35/5 = x
7 = x
Answer:
Part A: x= number of shifts he works at the theater y= number of dog-walking jobs.
Part B: The only terms are 85x and 15y.
Part C: 15y
Step-by-step explanation:
Part A: The variables are the xy reasoning to this is due to them being the replacements of the numbers which aren't known.
Part B: The terms are pieces of the expression which are together.
Part C: It is the one used above for the dogs " $15 for every dog-walking job."
