Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 13 left over. How many
chairs does Liam have?

Answers

We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.

This sets up a problem of:

6x + 7 = 4x + 13

7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.

x = 3

Knowing this, we plug in x for one of the equations

6(3) + 7
18 + 7
25

Liam has 25 chairs.

What is the relative frequency of selecting a club?

17%

20%

25%

30%

PLEASE ANSWER QUICKLY

Answers

Answer:

25%

Step-by-step explanation:

This is the answer because there are 4 different types of cards that can be chosen, the amount of trials is insignificant in this question. Since there are 4 types, there is a 1/4 chance of picking a club, another way to put this is 25%, thus giving your answer!

Answers

Answer:

Knee pain can have causes that aren't due to underlying disease. Examples include heavy physical activity, lack of use, injuries such as sprains or strains, sitting in a constrained area, or sitting on knees for a prolonged period.

Step-by-step explanation:

possibly Chondro malacia

Damage to the cartilage under the kneecap.

Symptoms may include

Knee pain

Cracking joints

Swelling of the knee

Please go to your doctor...ik it hard with cov id and everything

It could be hereditary, or it could just be a weak muscle. I have knee problems. If it’s just your knee cap that is dislocating you can do simple exercises to strengthen the muscle around it to hold it in place. If it’s your actual knee you should get it checked out to see if there is anything else going on. If it continues and there’s nothing “wrong” they’ll have you do physical therapy. When this dislocation happens, keep your knee up above your heart and ice it. After you pop it back on. And take pain relief. Wear a knee brace as well

For a school picnic, students are participating in a relay race. Each team has to fill a container that holds 200 liters of water, using bottles that hold 5 liters or 10 liters into the container. So far the blue team has poured ten 5-liter bottles and three 10-liter bottles into the container. How many more 10- liter bottles will the blue team need to fill the container

Answers

Since the blue team already poured ten 5 liters bottles so 10 x 5 = 50
And three 10 liters bottles so 3 x 10 = 30
Now you would add that up , 30 + 50 = 80
Then you subtract it from 200
200 - 80 =120
The last step is to divide by ten since it’s asking how many 10 liters bottles is need to fill the rest
120 divided by 10 =12
The blue team will need twelve 10 liters bottles to fill the container

Trend lines
Help will be greatly appreciated!
The manager of fast food restaurant collected data to study the relationship between the number of employees working registers and the amount of time customers waited in line to order. He made a scatter plot of the data and credited a trend line with the equation y= -70x+300, where y is the total amount of time waited in seconds and x is the number of employees working registers.
1. Did the scatter plot of data positive, negative, or no association? Explain your reasoning.
2. Maria went to the restaurant and waited 90 seconds to place her order. Use the trend line equation to predict how many employees were working.

when b = 2 and c = -3?

Answers

Answer:

Part A) − 12 b + 6 c + 18

Part B) -2b + 1c + 3

Part C) -4

Step-by-step explanation:

Part A)

Step 1:

-4b + -8b = -12b

Step 2:

8c + 2c = 6c

Step 3:

12 + 6 = 18

Answer: − 12 b + 6 c + 18

Part B)

GCF = 6

Step 1:

-12 divided by 6 = -2b

Step 2:

6 divided by 6 = 1c

Step 3:

18 divide by 6 = 3

Answer: -2b + 1c + 3

Part C)

Step 1: Subsitute 2 for b and 3 for c

(− 2 x 2 ) + (1 x -3) + 3

Step 2: Multiply (− 2 x 2 ) + (1 x -3) + 3

-4 + (-3) + 3
