Answer: Subtract 22 from both sides.
Step-by-step explanation:
f/3 +22 = 17
f/3 +22 -22 = 17 -22 Subtracting the same value from both sides keeps the equation equal.
Then simplify. The +22 and -22= 0 They "cancel" 17-22 = -5
f/3 = -17 f/3 is now isolated-- by itself-- in the equation.
<em>If you had to solve for f, the next step would be to multiply both sides by 3.</em>
Answer: None
The two sides of 2 and 3 combine to form 2+3 = 5. Imagine laying two sticks out of length 2 and 3. They would form a straight line and not be long enough to bend at the hinge to allow for the other side (size 5) to fit anywhere. A triangle does not form. Instead its simply a straight line. For a triangle to form, any two sides must add up to some value larger than the third side.
Answer:
12 ways
Step-by-step explanation
First, we will count the number of ways to get three correct answers:
Notice there is a set of 4 correct answers (one per each one of the four questions in the test). We need to pick three of them. The order does not matter (for example: it is the same to have the arrangement of correct answers: Question 1 , Question 2 and Question 3, than having the arrangement: Question 2, Question 1 and Question 3). Therefore, we are dealing with combinations from a set of 4 elements forming groups of 3 elements:
Now we need to count the number of ways we can answer incorrectly the remaining fourth question:
We have a total set of 3*4 = 12 incorrect answers (three per each one of the four questions in the test). But notice that once we have picked three correct answers, then we should exclude from the set of incorrect answers we can pick, those of the three questions already answered. So, we are left with just the set of incorrect answers of the remaining question that has not been responded yet. Thus, we just have 3 incorrect answer to pick for the remaining question.
Then using the fundamental counting principle, we multiply the previous results:
Ways to answer correctly three questions * Ways to answer incorrectly the remaining question
Therefore, there are 12 ways to fill out the answer sheet so that three answers are correct and one is incorrect.

Put it in Desmos, and it’ll show you
Answer:
A. 1/9
Step-by-step explanation:
In order to find probability, you need to add up the total number of cards Dana has.
14 + 10 + 8 + 4 = 36
Then set up a fraction representing probability.
4 hockey cards
---------------------
36 total cards
Simplify
1
---
9
This means that Dana has a 1 out of 9 chance of getting a hockey card.
