3. Draw a diagram of 1/5ths until it equals 15 (you'll need a total of 75 boxes)

4. the problem is 18z=72 so you need to divide 72 and 18. 72/18=4. therefore z equals 4.

5. make up a division problem that has the answer of 8. for example 24/y=3. y will equal 8. and then use a tape diagram for that.

6. make up a multiplication problem that has an answer of 8. for example 3y=24. y will equal 8. and then use a tape diagram for that.

7. Meghan is correct. when you have y divided by two you need to do the opposite and multiply both sides by two. Meredith was incorrect because she switched the division and multiplication signs completely which is not what you are supposed to do.

I will solve these equations algebraically.

Here you are:

1. 30= 5w

Divide each side by 5.

30÷5= 5w÷5

6 = w

∴ w= 6

To check,

30=5w

Substitute w for 6

30= 5 x (6)

30= 30

LS= RS

(You were correct, great job!)

12 = x÷4

Multiply each side by 4.

12 x 4 = x/4 x 4 ↔ 4 and 4 cancel out.

48= x

∴ x=48

Checking:

12= 48÷4

12= 12

LS=RS

y÷5=15

Multiply each side by 5.

y÷5 x 5= 15 x5

y =75

∴y=75

Checking:

Substitute y for 75.

y÷5=15

75÷5=15

15=15

LS=RS

18x=72

Divide each side by 18.

18x ÷ 18= 72÷18

x = 4

∴x= 4

Checking

18x=72

18(4)=72

72=72

LS=RS

I hope that these solutions helped you. I am sure that using the solutions, you can figure out the other questions on your own.

Answer:

the y-intercept is 7

Step-by-step explanation:

hope it helps. i just looked at the ordered pair and took the number that's on the y axis

Answer:

y=5x-3

Step-by-step explanation:

Slope intercept form is y=mx+b and you know the slope so you can get y=5x+b

Then you are given a point, (2, 7), so you can plug that into the equation to find the y-intercept

7=5(2)+b

Then you just solve for b

7=10+b

-10

-3=b

So the final equation is y=5x-3

The American Civil War (also known by other names) was a civil war in the United States from 1861 to 1865, fought between northern states loyal to the Union and southern states that had seceded to form the Confederate States of America. The principal cause of the war was the status of slavery in the United States, especially in the territories. After Abraham Lincoln won the November 1860 presidential election on an anti-slavery platform, an initial seven slave states declared their secession from the country to form the Confederacy. War broke out in April 1861 when secessionist forces attacked Fort Sumter in South Carolina, just over a month after Lincoln's inauguration. An additional four slave states joined the Confederacy in the following two months. The Confederacy grew to control at least a majority of territory in those eleven states (out of the 34 U.S. states in February 1861), and it claimed the additional states of Kentucky and Missouri by assertions from native secessionists fleeing Union authority. These states were given full representation in the Confederate Congress throughout the Civil War. The two remaining slave states, Delaware and Maryland, were invited to join the Confederacy, but Delaware declined and nothing substantial developed in Maryland due to intervention by federal troops. The Confederate states were never diplomatically recognized as a joint entity by the government of the United States, nor by that of any foreign country. The states that remained loyal to the U.S. were known as the Union. The Union and the Confederacy quickly raised volunteer and conscription armies that fought mostly in the South for four years. Intense combat left between 620,000 and 750,000 soldiers dead, along with an undetermined number of civilians. The Civil War remains the deadliest military conflict in American history, and accounted for more American military deaths than all other wars combined until the Vietnam War.

A data set has a mean of 7, a median of 5, and a mode of 8. Which of the numbers (7, 5, or 8) must be in the data set?

If possible, please explain in words, thank you. :)

Answers

5 must be in the data set: median means it’s the middle number in the set. so if the data was [2,3,5,6,7], 5 is the median.

8 has to be in the data set because 8 had to be there to be a mode were you can have 5 as the median if the set was like this 234678 because 4&6 both are in the middle so you have to do the middle of that which is 5 so that’s the median without having the number 5.

Each year thereafter, Tree A grew by 2 inches per year and Tree B grew by 5 inches per year. Let A A represent the height of Tree A t t years after being planted and let B B represent the height of Tree B t t years after being planted. Write an equation for each situation, in terms of t , t, and determine the height of both trees at the time when they have an equal height.

Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.75, and a package of folders for $3.75. What was the range of prices for the school supplies that Marty bought?

Answers

Answer:

$3.50

Step-by-step explanation:

to find the range you take the highest number and the lowest number and subtract them

so with that, let us do just that-

$5.75, $3.75, $3.25, $2.25

$5.75-$2.25

=$3.5

and since we're dealing with money we must add a '0' to the end of the decimal- $3.50

What is the mode for the set of data?
Ages
Stem Leaves

Answers

Answer:

Step-by-step explanation:

Because it's stem and leaves, the leaves are the digits DIRECTLY BEHIND the Stem.

74 appears 3 times which is the mode (most) in the set of data

Example:

1, 2, 4, 6, 10

(1 + 2 + 4 + 6 + 10)/5 = mean = 4.6

1, 2, 4, 6

(1 + 2 + 4 + 6)/4 = mean = 3.25

Because of this, mean does change when adding and removing outliers, and is therefor not the answer.

Median is the middle of the data. This is found by ordering the values in the data set from least to greatest (or greatest to least, either one works) and finding the number in the center of all the values. If there were an outlier, the median wouldn't be skewed as the mean is by outliers, but it would change.

Example:

1, 2, 4, 6, 10 Median = 4

1, 2, 4, 6 Median = 3

So median is not the answer, because it is affected by adding and removing outliers.

Mode is the value in a data set that appears the most. Outliers are numbers that are significantly lower or higher than most or all of the other numbers in a data set. Because of this, there can't be more outliers than other numbers, so it is impossible for the mode to be an outlier.

Example:

1, 1, 1, 2, 3, 4, 4, 86 Mode = 1

1, 1, 1, 2, 3, 4, 4 Mode = 1

This means the mode is not affected by adding and removing outliers.

Mode is a possible answer, but let's take a look at range before coming to a conclusion.

Range is the spread of values in a data set. In other words, the difference between the highest and lowest value. A high range can signal a possible outlier is present.

Example:

1, 2, 4, 6, 10

10 - 1 = highest value - lowest value = range = 9

1, 2, 4, 6

6 - 1 = highest value - lowest value = range = 5

The range is certainly affected by outliers, so it is not the answer.

Out of mean, median, mode, and range, the answer to this question is mode.

If an outlier is removed, mode will not change.

Hope this helps!

[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]

Find the area of the circle when C = 4π. Give your answer in terms of π.

Answers

Answer:

12.56

Step-by-step explanation:

So, the circumference will be 4(3.14), which is 12.56. So, now you can solve for area. By the way, the formula is: C = pi(d) (Just saying)

Anyways, A = pi(r)2. So, with the radius being half of the diameter, you will cut 4 in half. You are now ready to solve.

A = 3.14 (2) (2), which is 12.56 .
