Answer:

Consecutive whole numbers (or integers) are numbers that directly follow one another.

Eg: 1, 2, 3, 4, 5 are consecutive whole numbers.

Step-by-step explanation:

Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108.

let the three consecutive whole numbers is x, x+1,and x+2

x + x+1 + x+2 = 4+2(x+1)

3x+3=4+2x+2

3x-2x=6-3

x=3

the other two numbers are 3+1=4,and 3+2=5

so the three numbers are 3,4 and 5

The left side of equation is:

Simplifying the equation we get:

An equation has no solution when, we cannot find the value of x.

So, The order side of equation can be x

i.e,

Which ordered pair is a solution of the equation?<br> -3x – y = 6<br> Choose 1 answer:

Aleks [24]

Answer:

Step-by-step explanation:

I can not see your answers to choose but with this equation for 2 variables, you can replace the values of x and y and see if that is right or not.

For example, to know (-2,5) is a solution, you replace x= -2 and y= 5

into this equation: -3x -y = 6

and you have: -3*(-2) -5 =6

or 6-5 =6, and you find that is impossible, so (-2.5) is not a solution.

Hope you understand it

The area of a rectangular rug is given by the trinomial r^2 - 8r - 33. What are the possible dimensions of the rug? Use factori

Arte-miy333 [17]

Solve for r using factoring:
Solve for r:
r^2 - 8 r - 33 = 0

The left hand side factors into a product with two terms:
(r - 11) (r + 3) = 0

Split into two equations:
r - 11 = 0 or r + 3 = 0

Add 11 to both sides:
r = 11 or r + 3 = 0

Subtract 3 from both sides:
Answer: r = 11 or r = -3

There are 18 students on the debate club. How many ways can the club send 4 students to the next debate

olya-2409 [2.1K]

There are 3060 ways the club send 4 students to the next debate if there are 18 students on the debate club.

<h3>What is permutation and combination?</h3>

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have the total number of students = 18

The number of ways the club send 4 students to the next debate is:

= C(18, 4)

$= \rm \dfrac{18!}{4!(18-4)!}$
