22k - 39 = 11k + 2(10k+12)


PLEASE show your steps!

Answers

Answer: K = -7

Explanation:

22k - 39 = 11k + 20k + 24

22k - 39 = 31k + 24

22k - 31k = 24 + 39

-9k = 63

K = -7

Answer:

\(k=-7\)

Step-by-step explanation:

\(22k-39=11k+2\left(10k+12\right)\)

Apply the Distributive Property

\(22k-39=11k+20k+24\)

Combine like terms

\(22k-39=31k+24\)

Rearrange variables to the left side of the equation

\(22k-31k=24+39\)

Combine like terms

\(-9k=24+39\)

Calculate the sum or difference

\(-9k=63\)

Divide both sides of the equation by the coefficient of variable

\(k=-\frac{63}{9}\)

Cross out the common factor

\(k=-7\)

A pencil costs $3.50 and a pen costs $6.70. Jessica bought m pens. She also bought 4 fewer pencils than pens. Write and algebraic expression for the total amount she spent.

Answers

Answer:

Jessica bought X pens, which cost $6.70 each.

She also bought 4 fewer pencils than pens, or (X-4) pencils, at $3.50 each.

So in total, she spent:

6.7X + 3.5(X-4)

= 6.7X + 3.5X - 14

= 10.2X -14

So she spent $(10X - 14) on pens and pencils.

Step-by-step explanation:

Ok so Jessica bought M pens, which cost $6.70 each.

She also bought 4 fewer pencils than pens, or (M-4) pencils, at $3.50 each.

So in total, she spent:

6.7M + 3.5(M-4)

= 6.7M + 3.5M - 14

= 10.2M -14

So she spent $(10M - 14) on pens and pencils.

Which of the following statements are true of the algebraic expression 8y2 + 3y + 6? Select all that apply.

6 is a coefficient.
The expression has two variable terms.
8 is a constant.
This expression is the sum of three terms.

Answers

Answer:

The correct statements are:

6 is a coefficient.The expression has two variable terms.8 is a constant.This expression is the sum of three terms.

Explanation:

The coefficient is the numerical factor that is multiplied by a variable term. In this case, 6 is a coefficient that is associated with a constant term.Variable terms have a variable factor. In this case, the expression has two variable terms (8y^2 and 3y).A constant is a term that has no variable factor. In this case, 8 is a constant term.The expression has three terms: 8y^2, 3y, and 6. The term 8y^2 is a variable term, the term 3y is a variable term, and the term 6 is a constant term.

A simple math problem, but im terrible at math and need a refresher. HeLpP

Answers

Answer:13

Step-by-step explanation:

Calculate the quotient in the brackets (if you follow PEMDAS/BEDMAS, brackets come first.)

-4/12 = -0.33

-2/15 = -0.133

This gives you (-0.33)(-0.133)

Next, multiply both brackets together.

(-0.33)(-0.133) = appx. 0.044

Now that you have the product of the two brackets, calculate 5/6

5/6 = 0.833

Finally, sum it all up. Since the last two numbers are negative, we subtract them.

0.833 - 0.33 - 0.133 =

Answers

Answer:

the answer would be spinning a 3 and getting an even number on the number cube. read why below!

Step-by-step explanation:

because the spinner presents three options (two 2s, a 3 and a 1), there is a 50% chance that he will spin a 2. the spinner has to be able to represent his chances of having mr. muller as his science teacher though, because there is only a 25% chance that he will spin a 1 or a 3.

the number cube might be difficult to understand, but because there are 3 even numbers and 3 odd numbers, the chances of rolling an even or an odd number are equal: 50/50 chance, which represents his chances of having mrs. waugh as a teacher.

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value

Answers

The value of A/B is given as follows:

A/B = -2.

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?

2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100

Answers

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

2 over 8 equals j over 18

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

2 over 8 equals j over 18

Answer:

The answer is 4

Step-by-step explanation:

In triangle D the top side length is 8 and in triangle D' the top side length is 32. 32 is 4 times 8, and therefore D' was factored by a scale of 4 from D.

This can be done with each side:

8x=32 --> x=4 therefore the scale factor is 4

6x=24 --> x=4 therefore the scale factor is 4

The slope is -1/4 because slope = \(\frac{rise}{run}\),

So:

-\(\frac{1}{4}\) is the slope, also is negative.
