I think it may be:

n + (n + 1)

hope this helps

Two consecutive natural numbers would be 1 and 2, or 5 and 6, for example.

If the first number is n and the second number is n+1, then you are writing $n+(n+1)=2n+1$ .

What is the product of 2x + y and 5x – y + 3?

Radda [10]

Answer:

The product of 2x + y and 5x – y + 3 is 10x^2+ 3xy + 6x - y^2 + 3y

Step-by-step explanation:

The product of the two expressions can be expressed mathematically as;

(2x +y) (5x -y +3)

To obtain the product of these expressions, we simply expand the brackets as follows;

2x(5x -y +3) + y(5x -y +3)

= 10x^2 - 2xy + 6x + 5xy - y^2 + 3y

= 10x^2- 2xy + 5xy + 6x - y^2 + 3y

= 10x^2+ 3xy + 6x - y^2 + 3y

The product of 2x + y and 5x – y + 3 is thus 10x^2+ 3xy + 6x - y^2 + 3y

Mrs.gauthier plans to take her class on 2 field trips this year there are 23 students in her class and each field trip will cost

Alina [70]

If there is 2 field trips with 23 students and each student costs $5 dollars. So for the 1st trip it will be 23x$5

1st trip- $115

And on the second trip its the same because there is 23 students that cost 5 dollars so it will be 23x5

2nd trip- $115

To find out the total of both trips youd add 115+115/

In total, for both trips it will cost $230 dollars.

Answer:

see the explanation

Step-by-step explanation:

we know that

Alternate Exterior Angles are created where a transversal crosses two lines. Notice that the two alternate exterior angles are equal in measure if the two lines are parallel

In this problem

$m\angle x=67^o$ ----> by alternate exterior angles

One way to verify alternate exterior angles is to see that they are the vertical angles of the alternate interior angles

4x - 2y = 5 y= 2x + 10

Helga [31]

Answer:

There is no solution

Step-by-step explanation:

4x - 2y = 5 --> 4x - 2(2x + 10) = 5

4x - 4x - 20 = 5

4x - 4x -25 = 0

Final answer is -25 = 0 and so therefor it is no solution
