Answer: 15m + 5n

Step-by-step explanation:

so, first off, we take the number outside of the parentheses and multiply it by everything that's inside of the parentheses.

(5)3m + 5(n)

then, we just multiply all of those together.

15m + 5n

this is because when a negative multiplies with a positive ....it gives an answer of negative

Answer:

x=16

Step-by-step explanation:

[tex]x^{\frac{1}{2} }=64^{\frac{1}{3 } }=(4^3)^{\frac{1}{3} }=4^{3 \times \frac{1}{3} }=4 \\squaring\\x=4^2=16[/tex]

Answer:

1) line segment

2) square-root of 13.

3) plane F

4) Ray

5) I think the wrong image is attached, but a point would just be a dot, a line would have one dot then an arrow on the other end, an angle would be 2 lines connected with an emphasis on what's going on in between the 2 lines, a line segment is 2 dots on both ends of a line.

6)H N K I

7) (2,-8)

8) line p

9) (-2, 7)

Step-by-step explanation:

For the distance between 2 points, do (x2-x1)^2+(y2-y1)^2 then take the square root of that.

For naming a plane, as long as it is an uppercase cursive letter it is a plane.

Rays are lines without the dot on the end.

Collinear points are points that lie on the same line.

Midpoint method is finding the average between the x coordinates then the y coordinates, so think (x1+x2)/2, (y1+y2)/2, but this can be confusing with negative distances, so just think of it as on a number line, from -1 to -3 they are 4 apart, so the average between them is -2.

Answer:

16

Step-by-step explanation:

n-14=2

add 14 on both sides to get 16

In the statement, A number subtracted from 14 is 2 the unknown number

is 12.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, A number subtracted from 14 is 2.

Let the unknown number be 'n'.

∴ 14 - n = 2.

- n = 2 - 14.

- n = - 12.

n = 12.

Answer:

6

Step-by-step explanation: You can set up the equation: [tex]\sqrt{\frac{n}{3} }[/tex] = [tex]\sqrt{n-4}[/tex] You square both sides to cancel out the squares which leaves you with [tex]\frac{n}{3}[/tex] = n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with [tex]\sqrt{2}[/tex] on both sides.

Answer:

[tex]Outcome = \{4H,4T\}[/tex]

Step-by-step explanation:

Given

A roll of cube numbered 1 - 4

A flip of coin

Required

Determine the possible outcomes for a number greater than 3

First, we list the sample space of the coin:

[tex]Sample\ Space = \{1,2,3,4\}[/tex]

Next, we list outcomes greater than 3

[tex]S = \{3\}[/tex]

Next, we list out the sample space (C) of a flip of coin:

[tex]C = \{H,T\}[/tex]

Where

[tex]H = Head\\T = Tail[/tex]

So, the possible outcome for a number greater than 3 is:

[tex]Outcome = \{4\} + \{H,T\}[/tex]

[tex]Outcome = \{4H,4T\}[/tex]

Answer:

$7.25

Step-by-step explanation:

Total amount spent on the ticket   = $40.75

Number of ticket purchased  = 5

Processing fee per ticket  = $0.90

Unknown:

Cost of each ticket = ?

Solution:

To solve this problem, we need to find the processing fee for the 5 tickets purchase;

      Processing fee = number ticket x processing fee per ticket

      Processing fee  = 5 x 0.9  = $4.5

Now, the real cost a ticket = $40.75  - $4.5  = $36.25

So, cost per ticket is;

        Cost  = [tex]\frac{36.25}{5}[/tex]   = $7.25

Answer:

y = 1

Step-by-step explanation:

y is inversely proportion to x means that ,

y ∝ 1/x or ,

[tex]y\ \alpha\ \frac{1}{x}[/tex]

When we remove the proportionality sign we get,

[tex]y=k(\frac{1}{x})\\y=\frac{k}{x} \\[/tex]

now we know the point is (2 , 3) which means it corresponds to (x , y) which furthermore means y=3 when x=2,

so we insert these values and get the value of k.

[tex]y=\frac{k}{x} \\\\3=\frac{k}{2}\\\\6=k\\[/tex]

now the equation becomes,

[tex]y=\frac{6}{x}[/tex]

now we need to find y when x is 6 so just replace x with 6

[tex]y=\frac{6}{x}\\\\y=\frac{6}{6} \\\\y=1[/tex]

so we get the value of y is 1

Answer:

(300,15) [tex]\frac{y}{x}[/tex]=15/300=1/20

Step-by-step explanation:

How much money does Clare make after stuffing 1,500 envelopes?

Clare: y=1/10x=1/10(1500)=$150

How much money does Han make after stuffing 1,500 envelopes?

Han: y=1/20x=1/20(1500)=$75

What is Clare's rate of change?

1/10 means $1 for 10 envelopes

What is Han's Rate of change?

1/20 means $1 for 20 envelopes

Answer:

Liz got a higher score than Austin.

Step-by-step explanation:

Since 42 divided by 50 is 82, as a percentage is then 82%. Austin has a 80% which most likely means, if on the same quiz, that he got a 40 out of 50.
