D.) 4

Step-by-step explanation:

[tex]\frac{-4}{3}[/tex] ÷ [tex]\frac{2}{-6}[/tex]

To divide fractions, just flip the second fraction and multiply

[tex]\frac{-4}{3}[/tex] x [tex]\frac{-6}{2}[/tex] = [tex]\frac{24}{6}[/tex] = [tex]4[/tex]

Answer:

15-12+5.5+3-8

Step-by-step explanation:

15-12=3

3+5.5=8.5

8.5+3=11.5

11.5-8=3..5

Answer:

15-12+5.50+3-8=27.50

Step-by-step explanation:

You write the equation first and then find the answer.

Answer:

The expression “32” is a symbolic term. ... This means the term has variable meaning depending on which value is substituted for x. For example, if you set x=−2, you get (−2)2, another name for 4. x2−6x+4y (mentioned above) is symbolic term with two variables.

I hope that helps im only in 8th grade so I don't fully understand it either lol

x + 8y heres the answer

Answer: [tex]n=\frac{11}{10}[/tex]



Step-by-step explanation:

[tex]\frac{3n}{7}=\frac{33}{70}[/tex]

[tex]\frac{210n}{210}=\frac{231}{210}[/tex]

[tex]n=\frac{11}{10}[/tex]

Lol this question seems simple for a person coming from Calculus only to increase my confidence ; )

3n/7 = 33/70

So to solve this equation , all you have to do is cross multiply the fractions.

3n*70 = 33*7

210n = 231

n = 231 / 210 = 11/10

n = 11/10

Answer:

rate

Step-by-step explanation:

i think it is this bc i did this and it is correct

Answer:

D. rate

Step-by-step explanation:

A rate is a ratio that compares two different quantities that have different units of measure. A rate is a comparison that provides information such as dollars per hour, feet per second, miles per hour, and dollars per quart, for example. An example of this can be miles per hour or g/mL.

Step-by-step explanation:

Answer:

13/13.3 or 10

Step-by-step explanation:

You said she paid $10 to join, if she spent at least $40, then we subtract 10, then divide 30 by 3 then you would get 10.

If we don't have to subtract and she spent around $40 on only books, it would be 13/13.3

Answer:

Answer:

That is the slope intercept form

Step-by-step explanation:

Answer: The perimeter is 30ft.

Step-by-step explanation:

Let's define:

L = length of the longer side.

S = length of the shorter side.

P = perimeter

we know that for a common rectangle:

P = 2*S + 2*L

We aso know that:

L = 2ft + (1/3)*P

S = (1/10)*P

L = S + 9ft.

So we have a system, let's find the perimeter only using this system (So i will ignore the equation for the perimeter of a rectangle)

First, we can replace the third equation in the first equation, now we have a system with only two equations:

S + 9ft = 2ft + (1/3)*P

S = P/10

Now we can replace the second equation in the first equation, and get:

P/10 + 9ft = 2ft + P/3

Now let's solve this for P.

9ft - 2 ft = P/3 - P/10

7ft = P( 1/3 - 1/10) = P*( 10/30 - 3/30) = P*(7/30)

(30/7)*7ft = P = 30ft.

The perimeter is 30ft.

C.

y = 2 + 6r^4

Step-by-step explanation:

C.

y = 2 + 6r^4

Since this exponent is raised to a power, it is non-linear

Answer:

y = 2

Step-by-step explanation:

When we have graph is given also one value from x and y is given then for finding the other value, We simply see the line where x = -2 is graphed and then we will see what is the value of y there.

Answer below.

1. 2

2. 17

3. 16

4. 4

5. 2

6. 8

7. 8

8. 10

Answer:

5 units

Step-by-step explanation:

From the coordinates, we have;

x1 = -5

x2 = -1

y1 = 5

y2 = 2

Now,from the distance formula, distance is;

d=√((x2 - x1)²+(y2 - y1)²)

Plugging in the relevant values, we have;

d = √((-1 + 5)²+(2 - 5)²)

d = √(16 + 9)

d = √25

d = 5

Answer:

Science Test

Step-by-step explanation:

Math test:

24/30 so divide 24 by 30 to see the percentage she got, which is 80%

Science test:

21/25, same process as before, 21 divided by 25 is 84%

Therefore, she scored higher on the science test.

Answer:

x=5

Step-by-step explanation:

7 (x-8)=2x-31

Distribute the 7 to the x and -8 (basically multiple 7 with the x and -8)

7x-56=2x -31

Drag the 2x over to the other subtracting it from 7x.

7x-2x-56=-31

5x-56=-31

Drag the 56 to the other side and add it to -31

5x= -31+56 (or 56-31)

5x= 25

Divide 5x from 25 to get your X

x=25/5

x=5
