What is a division in mathematics?

Division is a mathematical operation that is used to determine the number of times one number, called the dividend, is contained within another number, called the divisor. The result of a division operation is called the quotient.

When a group of students share a certain number of items equally, it means that each student will receive the same number of items. To find out how many items each student will receive, we need to divide the total number of items by the number of students.

In this case, Mr. Novak gives 9 packs of paper to a group of 5 students. To find out how many packs of paper each student gets, we need to divide 9 by 5. We can use long division or use a calculator to find that 9 divided by 5 is 1 with a remainder of 4. So, each student will get 1 whole pack of paper, and the remaining 4 packs will be shared among the students. This can be written as a mixed number, which is a combination of a whole number and a fraction. In this case, the mixed number would be 1 4/5.

Hence, each student gets 1 whole pack of paper and 4/5 of a pack.

Well look at it this way.

It will just a smaller piece of something but never everything. For example 1/8 of 1/100000 is still going to be a number. So, it will never sell all video games. This is a mathematical perspective, not a logical perspective since logically you cant sell a part of a video game.

Answer:

f(-3)= -4

Step-by-step explanation:

Given function in the question is,

f(x) = 3x + 5

Here, values of 'x' are the input values of the function.

And the values of the function f(x) by substituting the values of 'x' are the output values.

If the output value of the function 'f' is -3,

-3 = 3x + 5

3x = -3 - 5

x = [tex]-\frac{8}{3}[/tex]

Therefore, for the input value x = [tex]-\frac{8}{3}[/tex], output value of the function will be f(x) = -3.

Answer:

As the ratio of the length of the arm of the old chair to the length of the arm of the new chair is 3/2, and the length of the old chair is 9 inches, hence the length of the arm of the new chair is 6 inches.

After substitution in the first equation :

7x + x +21 = -19

= 8x + 21 = -19

by subtracting 21 :

8x = -19 - 21

8x = -40

by dividing over 8 :

x = -5

after substitution in the second equation :

2y = -5 + 21

2y = 16

by dividing over 2 :

y = 8

Answer:

-7

Step-by-step explanation:

Since you are trying to solve for y, you set all the x values to 0.

(Y intercept occurs when x = 0, thats why you sub 0 for all x)

y= -4(0)^2[tex]y=-4(0)^{2} +5(0) -7[/tex]

this simplifies to

y=-7
