distributive property

Answers

In this problem, the distributive property is very important, but there is another thing that we can look at to make this much easier. We notice that the terms on the left are being multiplied by 6. We can rewrite the right side so that it is also a multiple of 6:

6(3c - 5d + 6) = 6(1)

Now, we can divide both sides by 6, and we get:

6(3c - 5d + 6) = 6(1)

3c - 5d + 6 = 1

3c - 5d = -5

Problem 10
(a) A teacher selects a team of three from a group of students. She also
selects a team of two (students can be in more than one team). The
teacher notices that there are twice as many ways of choosing the
team of three as there are the team of two. How many students are
in the group?
(b) For another group of students, there are three times as many teams
of three which can be selected as there are teams of two. How many
teams of three can be selected from this group?

Answers

Using the combination formula, it is found that:

a) There are 8 students in the group.b) 165 teams of three can be selected from this group.

---------------------------

The order in which the students are chosen is not important, which means that the combination formula is used to solve this question.

Combination formula:

is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

---------------------------

Question a:

3 students from a set of n, thus: [tex]C_{n,3}[/tex]2 students from a set of n, thus: [tex]C_{n,2}[/tex]

Twice as many ways to choose the teams of 3 than the teams of 2, thus:

[tex]C_{n,3} = 2C_{n,2}[/tex]

[tex]\frac{n!}{3!(n-3)!} = 2\frac{n!}{2!(n-2)!}[/tex]

We have to solve for n, thus:

[tex]2!n!(n-2)! = 2(3!)(n!)(n-3)![/tex]

[tex](n-2)! = 3!(n-3)![/tex]

From the factorial concept: [tex](n-2)! = (n-2)(n-3)![/tex], thus:

[tex](n-2)! = 3!(n-3)![/tex]

[tex](n-2)(n-3)! = 3!(n-3)![/tex]

[tex]n - 2 = 3![/tex]

[tex]n - 2 = 6[/tex]

[tex]n = 8[/tex]

There are 8 students in the group.

---------------------------

Question b:

First we have to find the total number of students, using the same logic as item a.

[tex]C_{n,3} = 2C_{n,2}[/tex]

[tex]\frac{n!}{3!(n-3)!} = 3\frac{n!}{2!(n-2)!}[/tex]

[tex]2!n!(n-2)! = 3n!3!(n-3)![/tex]

[tex]2(n-2)(n-3)! = 18(n-3)![/tex]

[tex]n - 2 = 9[/tex]

[tex]n = 11[/tex]

---------------------------

The number of teams of three is:

[tex]C_{11,3} = \frac{11!}{3!8!} = 165[/tex]

165 teams of three can be selected from this group.

A bag has 3 red marbles, 2 blue, 4 greens and 1 yellow. What is the probability of pulling a blue, putting it back
in the jar and then pull a green?
Show Your Work

Answers

Answer: 2/25

Step-by-step explanation: Since we are replacing the marbles, these two events are independent which means that the outcome of the first does not affect the outcome of the second.

First find the probability of selecting a blue marble.

There are 2 favorable outcomes, the blue marbles,

and 10 possible outcomes, all the marbles in the bag.

So the probability of selecting a blue marble is 2/10 or 1/5.

Always reduce when finding probability

Now we find the probability of selecting a green marble.

There are 4 green marbles and 10 total so the probability of

selecting a green marble is 4/10 or 2/5.

Now we multiply the probabilities.

So we have 1/5 x 2/5 or 2/25.

Explain how you can use absolute value to tell whether
the sum of two integers is positive or negative.

Answers

Answer:

Let the integers are p and q.

In case both integers are positive or negative, you add the numbers up and apply their sign to the sum.

Examples:

10 + 88 = 98-20 + (-15) = -35

In case one of the integers is negative and one positive.

p < 0, q > 0

Use absolute value in this case.

Subtract the numbers and apply the sign of the number with the greater absolute value.

Examples:

- 10 + 15 = |15 - 10| = |5| = 5- 15 + 10 = - |15 - 10| = - |5| = -5

Step-by-step explanation:

Let the numbers be x and y

If both are of same signs then

|x + y| = x + y

-|x + y| = -(x + y) = -x - y

If one is negative and one is positive

-|x + (-y)| = -|x - y| = -x + y

-|y + (-x)| = -|y - x| = -y + x

A wood board 59 inches long is cut into three parts. The first part is twice the

are the three parts?

Answers

Answer:

first part is 32 inches, second part is 16 inches, third part is 11 inches.

Step-by-step explanation:

4x + 64

x = 16.

we can then plug 16 in first parts expression, 2x, for 32. second part is just x so 16. 3rd part is 5 less, x-5, so 11.

47. n = -3

48. n = -15

49. n = -13/3

50. n = -17/3

Step-by-step explanation:

47.

6n + 4n = -30, so 10n = -30. Dividing by 10 on both sides, we get that n = -3.

48.

6n - 4n = -30, so 2n = -30. Dividing by 2 on both sides, we get that n = -15.

49.

6n - 4 = -30, so 6n = -26. Dividing by 6 on both sides, we get that n = -13/3.

50.

6n + 4 = -30, so 6n = -34. Dividing by 6 on both sides, we get that n = -17/3.

A trapezoid is regarded as a  quadrilateral that has only one pair of opposite sides that are said to be parallel.

It is made up of a right angles (called right trapezoid), and it can also contain a congruent sides (isosceles). Note that in the above, the only way the trapezoid  can fit into the translation movement (Point B)is if it is moved to the points of (x+1, y-3) on the graph.

The given translation is:

Karima earns $400 per week plus a holiday bonus of $250. Write an expression to represent the total amount she earns after working w weeks. Then, find the amount she earns after she works 4, 12, and 36 weeks.
Expression:
Earnings at 4 weeks:
Earnings at 12 weeks:
Earnings at 36 weeks:

Answers

Answer:

Step-by-step explanation:

Earnings per week = $ 400

Earning for 'w' week = 400*w + holiday bonus

                                   = 400w + 250

Earnings at 4 weeks = 400*4 + 250

                                   = 1600 + 250

                                   = $ 1850

Earnings at 12 weeks = 400*12 + 250

                                   = 4800 + 250

                                   = $ 5050

Earnings at 36 weeks = 400*36 + 250

                                   = 14400 + 250

                                   = $ 14650
