12 1/2 − 9 1/4
This problem comes from subtract mixed numbers
5 3/4 - 2 5/12
7 1/5 - 3 7/10
11 2/3 - 8 1/2

Answers

To convert a mixed number to an improper fraction, multiply the denominator by the whole number out front, then add the numerator. Keep the denominator. For example:

12 1/2 = 2 * 12 + 1 = 25/2
9 1/4 = 4 * 9 + 1 = 37/4

Multiply 25/2 by 2/2 to have a common denominator:
25/2 * 2/2 = 50/4

50/4 - 37/4 = 13/4 or 4 1/3

A bag contains 5 red marbles, 8 blue marbles and 4 green marbles. If three marbles are drawn out of the bag, what is the probability, to the nearest 10th of a percent, that all three marbles drawn will be red?

Answers

Without replacement, the probability that all three marbles drawn will be red is 0.01.

What is the probability?

Probabiliy is used to determine the likelihood of an event happening. The probability that the event would occur lies between 0 and 1.

Probability of drawing three red marbles = (number of red marbles / total number of marbles) x (number of red marbles / total number of marbles - 1) x (number of red marbles / total number of marbles - 1)

5/17 x 4/16 x 3/15 = 0.01

The probability, to the nearest 10th of a percent, that all three marbles drawn will be red; 1.5%

How to calculate probability?

We are given;

Number of red marbles = 5

Number of blue marbles = 8

Number of Green marbles = 4

Total number of marbles = 5 + 8 + 4

Total number of marbles = 17

Probability of first being red = 5/17

Probability of second being red = 4/16

Probability of third being red = 3/15

Thus;

P(all three marbles drawn are red) = (5/17) * (4/16) * (3/15)

P(all three marbles drawn are red) = 0.0147

Approximating to nearest tenth of a percent = 0.015 = 1.5%

you are buying decorations for a birthday party. the before tax total for 3 rolls of crepe paper and 20 balloons is $11.40. after you start decorating, you need more supplies. you buy 2 more rolls of crepe paper and 10 more balloons for $7.20 before tax. how much did each cost?

please help with an explanation.

Answers

Answer & Step-by-step explanation:

Let's have

C = Creepers

B = Balloons

1) 6C + 20B = 11.9  

2) 2C + 15B = 6.05

Eliminate

16C + 20B = 11.9 x3  

-2C + 15B = 6.05 x4

18C + 60B = 35.7  

-8C + 60B = 24.2

10C/10 = 11.5/10  

C = 1.15

A bag is filled with green and blue marbles. There are 43 marbles in the bag. If there are 7 more green
marbles than blue marbles, find the number of green marbles and the number of blue marbles in the bag.
Equation (use x as your variable):
The number of blue marbles is:____
The number of green marbles is:____

Answers

Answer:

Blue marbles: 18

Green marbles: 25

Step-by-step explanation:

First off, we have to define our variables.

g = # of green marbles

b = # of blue marbles

We know two equations:

g + b = 43 and g = b + 7

If you're wondering how I got the first equation, it was because the number of green and blue marbles is 43. For the second equation, we know that there are 7 more green marbles than blue marbles.

Now, we have an equation for the number of green marbles. We can plug that equation into the equation g + b = 43.

So, (b + 7) + b = 43.

When we simplify it, we get 2b + 7 = 43.

We subtract 7 from both sides, which gets us 2b = 36.

Now, b = 36/2.

b = 18.

So, we found out the number of blue marbles that we have. We know that g + b = 43. Now, all we have to do is plug in the number of blue marbles into that equation to find out the number of green marbles.

g + 18 = 43.

g = 43 - 18.

g = 25.

Thus, the number of green marbles we have is 25 and the number of blue marbles is 18.

y=5x-5
y= -4x+22

Answers

Substitution-

Step-by-step explanation:

y=5x-5

y= -4x+22

1- use y=5x-5 solve for y (here you don't really have to do anything)

       This stays the same, Therefore y = 5x-5

2- you will substitute y=5x-5 for y in y= -4x+22. The problem should now look like this:

               5x-5= -4x+22

Solving for x

now, with the equation above you will solve for x-

5x-5= -4x+22         (add 4x to both sides)

9x-5= 22               (add 5 to both sides)

9x=27                   (divide by 9)

x=3

Solving for y

Now that you Know that x=3 you can substitute x=3 for x in y=5x-5. The problem should look like this:

                                                    y= 5(3)-5

Now with the equation above you can solve for y

y= 5(3)-5              (multiply 5 by 3)

y= 15-5                 (subtract)

y=10

Now you have your answers X=3  Y=10

PLEASE HELP 100 POINTS!!! PLEASE DON'T ANSWER IF YOU DON'T KNOW!!
Alana and Kelsa are training for a marathon. To prepare for this marathon they have been training and tracking their progress periodically.

In the first week of training Alana ran an average of 20 minutes per mile. Later, in week seven of training she ran an average of 14 minutes per mile.

In the first week of training Kelsa ran an average of 15 minutes per mile. Later, in week five of training she ran an average of 13 minutes per mile.

Assuming that Alana and Kelsa continue to train and improve their times at the same rate your task is to determine which week they will have the same average minutes per mile. We will assume that the relationship is linear as they will be training for a maximum of 43 weeks. To complete this task follow the steps below.

1. Determine the equation of a line in standard form that represents Alana’s training progress. Her progress corresponds to the points (1, 20) and (7,14).

2. Determine the equation of a line in standard form that represents Kelsa’s training progress. Her progress corresponds to the points (1, 15) and (5,13)

3. Solve the system of equations (you must show all your work to receive full credit).

4. In which week will Alana and Kelsa have the same average minutes per mile?

5. If Alana and Kelsa continue to train until week 30, what will their times be?

6. Do you believe a linear model best represents the relationship of the time of the runners and the weeks that passed?(Hint: look at question 5). What do you think this says about problems in the real world? Justify your thoughts in 3-4 sentences.

Answers

Answer: Alana's training experience in (weeks, minutes per mile) is (1, 12) and (5, 6).

Kelsa's training experience is (1, 10), (11, 5).

Find:

A linear equation in standard form that describes Alana's experience

A linear equation in standard form that describes Kelsa's experience

A solution to the pair of linear equations

The week in which the number of minutes per mile is the same

Minutes per mile for Alana and Kelsa at week 25

Comment on the use of a linear model in this context

Solution:

Please note that in parts 1 and 2 a "standard form" linear equation has a positive leading coefficient and the numbers have no common factor.

1. A linear equation can be written from two points (x1, y1) and (x2, y2) as ...

... (y2 -y1)(x -x1) -(x2 -x1)(y -y1) = 0

Using the given points in order, this becomes

... (6-12)(x -1) -(5 -1)(y -12) = 0 . . . . above equation with values filled in

... -6x +6 -4y +48 = 0 . . . . . . . . . . eliminate parentheses

... 3x +2y -27 = 0 . . . . . . . . . . . . . divide by -2 to make x-coefficient positive

... 3x +2y = 27 . . . . . . . . . . . . . . . . Alana's training experience

2. In similar fashion, we can write the equation for Kelsa's experience.

... (5 -10)(x -1) -(11 -1)(y -10) = 0

... -5x +5 -10y +100 = 0 . . . . . . eliminate parentheses

... x +2y -21 = 0 . . . . . . . . . . . . . divide by -5

... x +2y = 21 . . . . . . . . . . . . . . . . Kelsa's training experience

3. We note that both equations have the term 2y, so we can subtract the second equation from the first to eliminate that term:

... (3x +2y) -(x +2y) = (27) -(21)

... 2x = 6 . . . . . . . simplify

... x = 3 . . . . . . . . divide by 2

... 3·3 +2y = 27 . . . substitute x=3 into Alana's equation

... 2y = 18 . . . . . . . . subtract 9

... y = 9 . . . . . . . . . . divide by 2

The solution is (weeks, minutes) = (x, y) = (3, 9).

4. The solution of part 3 tells us both have an average time of 9 minutes per mile in week 3 of training.

5. Substituting x=25 into the equations of parts 1 and 2, we get ...

... 3·25 +2y = 27

... y = (27 -75)/2 = -24 . . . . Alana's time per mile at week 25

... 25 + 2y = 21

... y = (21 -25)/2 = -2 . . . . . Kelsa's time per mile at week 25

6. A linear model makes no sense in this context. At some point a linear equation for minutes per mile will always have a value of 0. We know that marathon runners will never have a time of zero minutes per mile. Under the best of conditions, we expect training to improve time toward some asymptotic limit determined by body mechanics. A linear model is completely inappropriate for describing such training effects. Not every real-world problem is appropriately represented by a linear equation.
