Originally Dan has X amount of base ball cards.
So the equation would be
(x+6)/2=29
multiply both sides by 2
x+6=58
subtract 6
x=52
Check your work: 52+6=58/2=29
6x+ 3y+ 1 would be your answer because all you have to do is find the like terms and conbine them until you get your answer
To solve, you need to plug in the values they give you into the equation.
5t + 2m
Plug in the numbers they give you
5(2) + 2(7)
Solve.
10 + 14
Simplify.
24
Answer:D
Step-by-step explanation:9*3=27
27+25=52
Answer:
90.91% probability that a car needs an oil change given that it has a certain factory defect
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this problem, we have that:
Event A: having a factory defect.
Event B: needing an oil change.
The probability that a car has a certain factory defect is 825.
So 
The probability that a car has a certain factory defect and needs an oil change is 750.
So 
What is the probability that a car needs an oil change given that it has a certain factory defect

90.91% probability that a car needs an oil change given that it has a certain factory defect
