Answer:

In question 1, n= 16

In question 2, n = -1

Step-by-step explanation:

Question 1:       -3n + 48 =0

Question 2:        -2n + 10 - 5n = 17

<u>To find n in Question 1</u>

-3n + 48 =0

3n = 48

n = 48/3

n = 16

<u>To find n in Question 2</u>

-2n + 10 - 5n = 17

-2n - 5n = 17 - 10

-7n = 7

n = 7/-7 = -1

n = -1

Therefor the value of n in question 1 is 16

and value of n in question 2 is -1

Answer:

Problem 1: n = 16

Problem 2: n = -1

Step-by-step explanation:

Problem 1:

-3n + 48 = 0

We solve the equation for n.

First, subtract 48 from both sides.

-3n = -48

Now divide both sides by -3. This cancels out the negative on both sides:

n = 16

-2n + 10 -5n = 17

First, combine the terms with n:

-7n + 10 = 17

Now, combine the numbers that don't have n (subtract 10 from both sides).

-7n = 7

n = -1

Dennis and Connie purchased a radio for $128. Dennis paid $36 more than Connie. How much did each pay?
never [62]

Answer:

Dennis paid $82 and Connie paid $46.

Step-by-step explanation:

We can set up an equation by putting in variables, c representing how much Connie paid. Since we know that Dennis paid $36 more, we will also factor that in the equation.

c + c + 36 = 128

Where c + 36 represents the amount Dennis paid, and 128 represents the total amount paid as given in the question. We can start by adding like terms. 2c + 36 = 128

Now, we can subtract 36 from each side,

2c + 36 - 36 = 128 - 36

2c = 92

Divide each side by two,

2c/2 = 92/2

c = 46

Now, to make sure this is correct, let's substitute our c for 46 in our equation:

46 + 46 + 36 = 128

92 + 36 = 128

128 = 128

Therefore, our equation is correct, and Dennis paid $82 while Connie paid $46.

What is the slope of line PQ?
Scilla [17]

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

<u>Part a) Find the slope of line PQ</u>

P(-8,2)\ Q(4,2)

substitute in the formula

m=\frac{2-2}{4+8}

m=\frac{0}{12}=0

Any line parallel to X-axis has slope equal to zero

so

the line PQ is parallel to the x-axis

therefore

<u>the answer Part a) is </u>

0

<u>Part b) Find the slope of line MN</u>

M(8,6)\ N(8,-8)

substitute in the formula

m=\frac{-8-6}{8-8}

m=\frac{-14}{0}

Anything divided by zero is undefined

m=undefined

therefore

<u>the answer Part b) is </u>

undefined

<u>Part c) How are the two lines related ? </u>

we know that

Any line perpendicular to X-axis has slope undefined

Because the term (x2-x1) will always be zero

so

<u>the answer Part c) is</u>

the lines are perpendicular
