Two students participated in a fund-raiser. Each sold a combination of pencils and notebooks. The first student sold 2 pencils and 8 notebooks for a total of $17. The second student sold 10 pencils and 3 notebooks for a total of $11. Find the price of each item.Write a system of equations (two equations), and define the variables also.

Answers

2x + 8y = 17
10x + 3y = 11

We need to solve the system of equations.

x = pencils
y = notebooks

If we solve by graphing, we get the answer:

One pencil costs 0.50 dollars
One notebook costs 2.00 dollars

IS 0.6 GREATER THAN OR LESS THAN OR EQUAL TO 0.60

Answers

0.6 is not less than or greater than 0.60 it is equal to 0.60, and both numbers are equal.

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

We have:

Two decimal numbers 0.6 and 0.60

We can write 0.6 as:

= 0.6 = 6/10

Similarily,

We can write 0.60 as:

= 0.60 = 60/100 = 6/10

0.6 = 6/10

0.06 = 6/10

Thus, 0.6 is not less than or greater than 0.60 it is equal to the 0.60, both numbers are equal.

Equals to. As 0.60 could also be written as 0.6 or 0.600 ( the difference would be the amount of decimals but the value is the same )

Answers

Answer:

$\large\boxed{(x+y)^2:(x-y)^2=49}$

Step-by-step explanation:

$3x=4y\qquad\text{subtract}\ 3y\ \text{from both sides}\n\n3x-3y=y\qquad\text{distributive}\n\n3(x-y)=y\qquad\text{divide both sides by 3}\n\nx-y=(y)/(3)\qquad(*)\n------------------\n3x=4y\qquad\text{add}\ 3y\ \text{to both sides}\n\n3x+3y=7y\qquad\text{distributive}\n\n3(x+y)=7y\qquad\text{divide both sides by 3}\n\nx+y=(7y)/(3)\qquad(**)\n------------------$

$(x+y)^2:(x-y)^2=((x+y)^2)/((x-y)^2)\qquad\text{use}\ \left((a)/(b)\right)^n=(a^n)/(b^n)\n\n=\left((x+y)/(x-y)\right)^2\qquad\text{substitute}\ (*)\ \text{and}\ (**)\n\n=\left(((7y)/(3))/((y)/(3))\right)^2=\left((7y)/(3)\cdot(3)/(y)\right)^2\qquad\text{cancel}\ 3\ \text{and}\ y\n\n=(7)^2=49$

Answers

Answer:

The reasonable domain is the set of natural numbers.

Step-by-step explanation:

When we talk about a reasonable domain for a function, we refer to all values inside the domain set that makes sense to the problem which models the function. For example, if the function models people's age, then the reasonable domain must be all positive integers.

In this case, we have the function

$f(x)=3.25x$

Where $x$ represents the number of cars.

The mathematical domain refers to the comple domain set, using negative and positive numbers. However, the mathematical domain doesn't make sense to this problem, because the domain represents cars, and they cannot be represented by negative numbers and decimals.

So, the reasonable domain to this function is the set of all natural numbers, because they are positive and integers.
