Answers

Answer:

Step-by-step explanation:

First, find the total number for the set of four numbers. To do this, multiply 3.5 and 4. We do this because the mean is division, so we need to get back to the original amount.

3.5 x 4 = 14

Next, we need to find the other total when the mean is 4. There are 5 numbers, which tells us we had to divide the total by 5 to get 4. So, again, we want to multiply the mean, 4, and the 5 to get the total.

5 x 4 = 20

Finally, find the number we added in. To do this, we subtract the two totals.

20 - 14 = 6

Answers

Answer:

m∠1= 31° m∠2=149°

m∠3= 31° m∠4=149°

m∠6=31° m∠7=149°

m∠8=31°

Step-by-step explanation:

m∠1 + m∠5= 180°

m∠1=180-149

m∠1=31°

m∠2+m∠1=180

m∠2=149°

m∠6=31°

m∠3=m∠1 (corresponding angle)

m∠3=31° m∠8=31° (vertical angle)

m∠4=149° m∠7=149° (vertical angle)

Slope Formula:

[tex]\bold{\displaystyle\frac{y_2-y_1}{x_2-x_1}}[/tex]

Where

[tex]\bold{y_2}[/tex] is the y-coordinate of the second point

[tex]\bold{y_1}[/tex] is the y-coordinate of the first point

[tex]\bold{x_2}[/tex] is the x-coordinate of the second point

[tex]\bold{x_1}[/tex] is the x-coordinate of the first point

Check the First example:

[tex]\bf{y_2}[/tex] = 6

[tex]\bf{y_1}[/tex]= -2

[tex]\bf{x_2}[/tex]=3

[tex]\bf{x_1}[/tex] = -9

Plug in the Values

[tex]\bf{\displaystyle\frac{6-(-2)}{3-(-9)} }[/tex]

6-(-2) is the same as 6+2; same with 3-(-9)

[tex]\bf{\displaystyle\frac{6+2}{3+9}}[/tex]

Simplify:

[tex]\bf{\displaystyle\frac{8}{12}}[/tex]

Is the slope negative? Nope!

How about Option B?

[tex]\bf{\displaystyle\frac{7-9}{5-6}}[/tex]

[tex]\bf{\displaystyle\frac{-2}{-1}}[/tex]

Right now it seems like the slope's negative, huh? Well, wait for it...

We have 2 options left: C & D.

[tex]\displaystyle\frac{-8-1}{8-(-8)}[/tex]

[tex]\displaystyle\frac{-8-1}{8+8}}[/tex]

[tex]\displaystyle\frac{-9}{16}}[/tex]

We did it! The slope's actually negative :)

How about Option D (just to make sure the third option is right)

-9-(-8)/-1-2

-9+8/-3

-1/-3

Again we have a negative over a negative.

Therefore, the correct option is

A lawyer spends $75.00 on 3 staplers and 3 pads of paper. If each stapler costs $21.75, and each pad of paper costs x dollars, which statement is true?

Answers

Each pad of paper cost 3.25. Here is how I found it.

21.75 x 3 = 65.25
75 - 65.25 = 9.75
9.75 / 3 = 3.25

X = 3.25

Is this what you were looking for?

If staplers cost 21.75 each and there’s 3, you would need to do 21.75x3=65.25
You have 9.75 left for pads of paper and there’s 3 so 9.75/3=3.25

Each pad of paper costs $3.25 or x=3.25
