Answer:

the answer is 50

Step-by-step explanation:

first you plug in the x and y in the equation, making it 6(7)=-4(-2) then, you multiply the numbers together, making the equation 42+8. finally, you add those numbers together, giving you the answer 50

It's 50. Just multiply 6 times 7 and you get 42. Then you multiply 4 times -2 which is -8 . Then you subtract the products and you get 50. Your welcome.

Everett is rolling a block with the numbers 1, 2, 3, 4, 5, and 6 on it. Finley is drawing one disk from a basket of three disks:

ioda

Option A:

The probability that Everett and Finley end up with an even number and a blue disk is $\frac{1}{6}$ .

Solution:

Given data:

Everett is rolling a block with numbers = {1, 2, 3, 4, 5, 6}

Finley is drawing one disk from basket with colors = {blue, red, yellow}

Total number of numbers = 6

Total number of colors = 3

$$\text { Probability }=\frac{\text {Number of possible outcomes}}{\text {Total number of outcomes}}$

$P\text{(Even number)} =\frac{3}{6}$

$P\text{(Blue disk)} =\frac{1}{3}$

$P\text{(Even number and Blue disk)} =\frac{3}{6}\times\frac{1}{3}$

$$=\frac{3}{18}$

Divide numerator and denominator by the common factor 3.

$$=\frac{3\div3}{18\div3}$

$$=\frac{1}{6}$

Option A is the correct answer.

Hence the probability that Everett and Finley end up with an even number and a blue disk is $\frac{1}{6}$ .

Solve 5n – 7p + 3n = 25p for n.

saul85 [17]

5n – 7p + 3n = 25p

Combine like terms

8n - 7p = 25p

Add (7p) to both sides

8n - 7p + 7p = 25p + 7p

Simplifying

8n = 32p

Divide both sides by 8

8n / 8 = 32p / 8

Simplifying

n = 4p

The number of comic books is an illustration of a linear function

The complete equations are: $\mathbf{8b + 17 =65}$ and $\mathbf{b =6}$
The value of b has increased by 4

She had 17 comic books already.

So, we have:

$\mathbf{Base\ Amount = 17}$

Her order of 65 books contains 8 comic books per collection.

So, we have:

$\mathbf{Rate = 8}$

$\mathbf{Total = 65}$

This is represented as:

$\mathbf{Rate \times b + Base\ Amount =Total}$

So, we have:

$\mathbf{8\times b + 17 =65}$

Rewrite as:

$\mathbf{8b + 17 =65}$

Subtract 17 from both sides

$\mathbf{8b =48}$

Divide both sides by 8

$\mathbf{b =6}$

Assume she has 97 books in her collection, then the equation would be represented as:

$\mathbf{8b + 17 = 97}$

Subtract 17 from both sides

$\mathbf{8b = 80}$

Divide both sides by 8

$\mathbf{b = 10}$

The values of b are 6 and 10.

The difference between 6 and 10 is 4

Hence, the value of b has increased by 4

I NEED HELP ASAP First, find the increasing functions. Then, classify each increasing function as having a larger or a smaller u

aev [14]

Answer:

In descending order the function are represented as $D>F>A>B>E>C$

Step-by-step explanation:

Whether it is increasing or is the larger or smaller number it all depends on its slope.

Equation of line $y=m(x)+c$ ,and $m$ is the slope.

So we will work with the slopes of each equations and arrange them in descending order.[Greater to larger number sequence]

Slopes are $\frac{4}{3}, \frac{5}{4}, \frac{-2}{1},\frac{7}{4}, \frac{6}{5}, \frac{8}{5}$

We will equate the denominator by taking LCD of it then multiply numerator and denominator with a fix number which can bring all the denominator same.

LCD of the denominator $(1,3,4,5)=60$
