Write fractions for points A and B on the number line. (yup, I'm dumb)

Answer:

how many does it have left noob

Answer:

The first one is 30

Step-by-step explanation:

Answer:

[tex]y=13\text{ miles per gallon}[/tex]

Step-by-step explanation:

We have the two points: (0, 11) and (3, 50).

And we want to find the rate of change in y relative to x, where x is the gallons and y is the miles.

In simple terms, we want to find the slope between the two points.

So, let's use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, 11) be (x₁, y₁) and let (3, 50) be (x₂, y₂). Substitute. Let's also put "miles" in the numerator with the Ys and "gallons" in the denominator with the Xs. This yields:

[tex]y=\frac{50-11\text{ miles}}{3-0\text{ gallons}}[/tex]

Subtract and reduce:

[tex]y=39\text{ miles}/3\text{ gallons}=13\text{ miles per gallon}[/tex]

And we're done!

Answer:

1. f > 40 miles/gallon

2. t < 35 degrees

Answer:

For part one the vehicle cannot have less than 40mpg so the equality would be

[tex]f\geq 40mpg[/tex] because the mpg must be greater than or equal to 40mpg.

For part two the temp must be LESS than 35 not including 35.

so we would show that with [tex]t<35F[/tex]

Answer:

5 movies

Step-by-step explanation:

Let x denotes number of movies that need to be ready each month for the total fees to be the same from either company.

Monthly membership fee charged by a video store = $7.50

Amount charged to rent each movie = $1.00

So,

total amount charged by the first store = [tex]7.50+(1)x=7.50+x[/tex]

Monthly membership fee charged by another video store = $0

Amount charged to rent each movie = $2.50

So,

total amount charged by another store = [tex]0+2.50(x)=2.50x[/tex]

To find number of movies that need to be ready each month for the total fees to be the same from either company,

solve [tex]7.50+x=2.50x[/tex]

[tex]7.50+x=2.50x\\7.50=2.50x-x\\7.50=1.50x\\x=\frac{7.50}{1.50}\\ =5[/tex]

Answer:

Two slices cost $2.20, 10 slices cost $11, and half a slice costs $0.55

Step-by-step explanation:

First, find the cost of one slice, by dividing 5.50 by 5

5.50/5

= 1.10

Then, multiply this by 2, 10, and 1/2, to find the cost of those numbers of slices.

1.10(2)

= 2.20

1.10(10)

= 11

1.10(1/2)

= 0.55

So, two slices cost $2.20, 10 slices cost $11, and half a slice costs $0.55

Answer:

see below

Step-by-step explanation:

First find the unit rate

$5.50 / 5 slices = $1.10 per slice

2 slices

$1.10 *2 = $2.20

10 slices

$1.10 *10 = $11.00

1/2 slice

$1.10 *.5 = $0.55

Answer:

64

Step-by-step explanation:

Its practically just 8 times 8

y + 82 = 10x is the answer.

Answer:

y+72 = 10(x-1)

Step-by-step explanation:

I don't really know why this would be useful for solving a problem; please tell me in the comments of my answer.

Anyway, I would pick a random point that would satisfy this equation. One example would be (1, -72)

Now just plug those 2 numbers into the equation:

y+72 = 10(x-1)

Answer:

the value of X is 13..

Answer:

2

Step-by-step explanation:

subtract 3 from the 3 and 3 from 11 which would give you 8 then you would divide the 4 from 4a which would leave you with just a and then divided 4 by 8which would give you 2 so its a=2

Answer:

Subtraction

Step-by-step explanation:

Subtraction.

11x + 3 = 3

We need to isolate x.

Therefore, we have to move anything unrelated to the other side first.

Then, we can take the things directly affecting x off first.

-3 comes first, then divide by 11.

11x + 3 = 3

      - 3    - 3

11x = 0

x = 0

Answer:

The answer is subtraction.

-38y-21z

Step-by-step explanation:

-2(3y+z)-7z-4(3z+8y) is the same as

-6y-2z-7z-12z-32y which is the same as

-38y-21z Which is in simplest form

Answer:

-21z-38y

Answer:15

Step-by-step explanation:

Answer:

r = 1/2(s -t/x)

Step-by-step explanation:

Here, we simply want to make r the subject of the formula;

We proceed as follows;

s = 2r + t/x

s - t/x = 2r

Divide both sides by 2

r = 1/2(s - t/x)

Answer: B

Step-by-step explanation:

To get no solution you need to have 2 sides of the equations that don't match. If you go through B you will end up getting 3x- (11/7)=3x-2 which is not true.

Answer:

A

Step-by-step explanation:

It is A because it is very precise and it can make a bar graph.

Answer: Choice A) You ask 20 people what their favorite season is.

Choices B and C are best represented with a line graph to show the growth over time.

A bar graph is useful to see how many categories get a certain response. In the case of choice A, we have four categories for each season. The height of each bar represents how many responses were made for that given category.

Answer:

5 times

Step-by-step explanation:

Answer:

5 times

Step-by-step explanation:

So this is called division. To solve this you can either use a calculator, or you can use something called guess and check. Guess and check is what it sounds like, guessing and checking to see if it's correct or not.

The way I would solve it is just do 100/20 which equals 5. You can also just add 20 a certain amount of times. For example you could do 20 + 20 + 20 + 20 which equals 80. So that means you can add another 20 to equal 100

Answer:

20

Answer:

100 ft.

Explanation:

To find an area, you have to multiply the length/width of every side. Meaning you just have to do simple multiplication, which is:

20x4= 80

200x4= 800

100x4= 200

25x4= 100

As you can see, it is 100.

Answer:

65 marbles

Step-by-step explanation:

2:6 = x-20:x using the information in the problem

2x = 6x-120, and therefore x = 30. 30 is the number of green marbles.

We can find that the multiplier is 30/6 = 5. So there will be 5*2 = 10 red marbles. 5*5 = 25 blue marbles.

30+10+25 = 65 marbles total.

Answer:

A- Confident

Answer: D. intelligent

Answer:

Step-by-step explanation:

Refer to attached

With a corner removed, it doesn't change surface area of the cube as same area is exposed equal to the area of 3 small faces.

With the corner relocated to the top of the cube, it covers the area of one small face but adds up small 5 faces (4 sides and one top). In total the P has more surface area than the Q.

Correct answer choice is C.

Answer:

6/7 = y

Step-by-step explanation:

-3=7(y-9/7)

Distribute

-3= 7*y - 7*9/7

-3 = 7y - 9

Add 9 to each side

-3+9 = 7y -9+9

6 = 7y

Divide each side by 7

6/7 = 7y/7

6/7 = y

Answer: 57.02

130.3 - 73.28 = 57.02
