Graph the solutions, if possible.

Answers

Answer 1

Answer:

Answer: No Solution

Step-by-step explanation:

When there are absolute values on both sides, you simply just get rid off the signs. (Normally, it results in positive and negative on the other side)

SOLVE:

Given

|-9-7x|=|23-7x|

No absolute value sign

-9-7x=23-7x

Add 7x on both sides

-9=23

ANSWER:

This is no solution, because -9≠23

You own 6 hats and are taking 4 on vacation. In how many ways can you choose 4 hats from the 6?A. 15

B. 360

C. 1

D. 720

Answers

Answer:

Option B is the answer.

Step-by-step explanation:

I own 6 hats and i am taking 4 hats on vacations.

I have to find the number of ways that I can choose 4 hats out of 6.

In this question we will apply the combination rule.

So by combination rule number of ways to choose hats will be $^(6)C_(4)$

$^(6)C_(4)=(6!)/((6-4)!(4)!)$

$=(6* 5* 4!)/(2!* 4!)$

$=(30)/(2)$

=15

Therefore, option A. 15 will be the answer.

your answer is A. 15

Answers

45 minutes : 1 hour

We need to make the units the same! This is crucial! If you do not have the proper units the whole answer is wrong!

45 minutes : 60 minutes

These are both divisible by 15:

3 minutes : 4 minutes

So, the ratio is 3 : 4

Final Answer: 3:4

Here, we need to write a ratio. A ratio compares two quantities.

45 to 1 hour

A bag contains 9 red chips and 12 blue chips. Two chips are selected randomly without replacement from the bag. What is the probability that the two chips are the same color?That would be the probability of two reds PLUS the probability of two blues.
The probability of two reds is (9/21)*(8/20) = 72/420 The probability of two blues is (12/21)*(11/20) = 132/420. The sum is 204/420 = 51/105 = 45.87% A magician asks you to pick a card, any card from a standard deck of 52 cards. What is the probability of picking an ace?

Answers

Since you already answered the first question, I'll answer the other two

1. There are four aces and 52 cards. Just divide 4 by 52 to get 1/13, or about 7.69%.

2. If you mean the probability of choosing white from the handful, that's (15-10)/15, or 1/3 (33.33%). However, in the mixture itself (combined with the handful), that's 300/1500, or 20%.
