9514 1404 393

Answer:

  1) W = 10

  2) x = 33/2

Step-by-step explanation:

These are 2-step linear equations. Step 1: Add the opposite of the constant on the right. Step 2: Divide by the coefficient of the variable.

__

1) 15 = 2W -5

  20 = 2W . . . . . add +5

  10 = W . . . . . . . divide by 2

__

2) 24 = 2x -9

  33 = 2x . . . . . add +9

  33/2 = x . . . . divide by 2

_____

As always, whatever you do to one side of the equation must also be done to the other side. That is, the same number is added to both sides; both sides are divided by the same number.

Ms. Moneyhun's son, Sam, just learned to crawl. He can crawl 20 ft in one minute. How many feet can Sam crawl in one hour? (Hint: there are 60 minutes in one hour)​

Answers

Answer:

1200 ft in one hour

Step-by-step explanation:

The ratio of Sam crawling 20 ft in one minute can be written as:

20:1

Multiply the ratio by 60 to get the minutes to 60 minutes, because there are 60 minutes in an hour:

 20    :    1

×60     ×60

To get:

1200:60    This means Sam can crawl 1200 ft in 60 minutes, which is the same as 1200 ft in one hour.

The number of water bottles used during a teams football practice varies directly with the temperature. If a team uses 75 water bottles when the temperature is 60 degrees, what is the temperature if they use 120 bottles?

Answers

Answer:   If a team uses 75 water bottles when the temperature is 60 degrees, ( 75 - 15 = 60 )

I guess if they have 120 bottles, you'd have to take away 15 again, which = 105

Answers

Answer:

12345

Step-by-step explanation:

give me a brainliest plees

Answer:

you can create your box plot from the following answers

a) minimum = 13

b) first quartile = 17

c) median = 22.5

d) third quartile = 26.5

e) maximum = 32

e) interquartile range = 26.5 - 17 = 9.5

Step-by-step explanation:

minimum and maximum values are self-explanatory

first quartile is derived by getting the median of the lower half of data (the median will divide the data into the lower half and the upper half)

third quartile is derived by getting the median of the upper half of data

the median is sometimes referred to as the second quartile

box plots are all about quartiles so that you can see where 25% of the data reside, or 50% or 75%, etc

Is 5 a solution to the equation x + 3 = 8

Answers

yes because when you replace x with 5 you get the equation 5+3=8 and 5+3 is in fact 8 so 8=8
Answer:  [tex]\boxed{x=5}[/tex]Solution Steps:

______________________________

1.) Subtract 3 from both sides:[tex]3-3=[/tex] Cancels Out[tex]8-3=5[/tex]

 - When solving problems like these (One-Step Equations,) to get x alone you must do the opposite of what you see.

- In this situation we have a positive 3. So to get rid of both numbers you do the opposite: Opposite of +3 is -3. So you subtract 3 from each number.

a long-distance telephone call costs $1.65 for the first 3 minutes and $0.42 for each additional minute. how much will a 23-minute call cost​

Answers

Answer:

About $43.69.

Step-by-step explanation:

1.65+0.42t=20 you minus the 3 minutes from the 23 minutes because those are paid for by the 1.65. Then for every extra minute, you pay 42 cents.

1.65+0.42t=20

Subtract the 1.65

0.42t=18.35

t≈43.69

Erica purchased adult and youth tickets for a movie. She bought x adult tickets for $7 each and y youth tickets for $5. Write an expression that can be used to show the total cost, C, of all tickets.


PLZ HELP IM FALING :o

Answers

Answer:

C = 7x + 5y

Step-by-step explanation:

Algebraic Expressions

Erica purchased tickets for a movie. It's given each adult ticket cost $7 and each youth ticket cost $5.

If each adult ticket cost $7 and she bought x tickets, then she spent 7x dollars on adult tickets.

Similarly, if each youth ticket cost $5 and she bought y tickets, then she spent 5y dollars on youth tickets.

The total cost C is the sum of the individual costs, thus:

C = 7x + 5y

There are $7 for EACH person so u multiply. Same as $5 and y. (So 7x+5y)

WORTH 15 POINTS!! - Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.

3.5
3.25

0.25

Answers

Answer:

0.25

Step-by-step explanaition:

The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

A school district has decided that students in grades 7 through 12 should receive 400 minutes of physical education every 10 school days. A gym teacher at one of the schools believes that his students are not meeting this criterion. She randomly selects 50 students and it is found that her students have a mean of 385 minutes and a standard deviation of 55 minutes. Is this evidence to support her claim?

Answers

Answer:

Yes

Step-by-step explanation:

Based on the information provided we can say that Yes, this is enough evidence to support her claim. Since the 50 students were randomly selected and the physical education criteria applies to all of the students in that grade range then these 50 students perfectly represent the total population. That being the case, the results gathered to show that with a standard deviation of 55 minutes some students are surpassing the requirement by very little but others are falling very far from that requirement. When it is a requirement for all of the students in that grade range. Therefore, it is enough to support her claim.

A triangle has side lengths of (1.3k+3.5m)(1.3k+3.5m) centimeters, (4.1k-1.6n)(4.1k−1.6n) centimeters, and (9.7n+4.4m)(9.7n+4.4m) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

Answers

Answer:

(5.4k+7.9m+8.1n) centimeters

Step-by-step explanation:

Given the side length of a triangle;

S1 = (1.3k+3.5m) cm

S2 = (4.1k-1.6n) cm

S3 = (9.7n+4.4m) cm

Perimeter of the triangle = S1+S2 + S3

Perimeter of the triangle = (1.3k+3.5m) + (4.1k-1.6n) + (9.7n+4.4m)

Collect the like terms;

Perimeter of the triangle = 1.3k+4.1k+3.5m+4.4m-1.6n+9.7n

Perimeter of the triangle = 5.4k+7.9m+8.1n

Hence the expression that represents the perimeter of the triangle is (5.4k+7.9m+8.1n) centimeters

Cheddar cheese cost 4.25 per pound. Which equation best represents y, the cost of x pound of cheddar cheese

Answers

Answer:

y = 4.25x

Step-by-step explanation:

Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as

4.25 is the cost for 1 pound of Cheddar cheese

Let the cost of the equation be y as required from the question.

y = cost of the cheddar cheese

x is the weight value in pounds of the Cheddar cheese.

The equation can be best represented as

y = 4.25x

In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.
