Answer:

A ) ( 5 ,0 ) .

Step-by-step explanation:

Given  : 2x + y = 10

y = x – 5.

To find : Use the substitution method to solve the system of equations.

Solution  : We have given

2x + y = 10 -------(1)

y = x – 5---------(2).

Plug y = x -5 in equation 1

2x + x - 5  = 10 .

3x -5 = 10 .

On adding both sides by 5 .

3x = 10 + 5 .

3x = 15

On dividing by 3 both sides

x = 5 .

Now,  plug x = 5 in equation 2

y = 5 -5

y= 0 .

( 5 ,0 )

Therefore, A ) ( 5 ,0 ) .

Can someone please help super short
insens350 [35]

Answer:

542, 543, 544, 545.

Step-by-step explanation:

Divide 2174 by 4 = 543.5  

(because there are 4 integers) 543.5 is not an integer.

However, one of the four integers is 543.

Write down four consecutive numbers that include 543 and add them:  

like 541+542+543+544 =. if that is 2174, you have the answer, if it's too low, try moving up one number, like

542+543+544+545 = if it's still too low, move up one number again  

543+544+545+546=  

You only have to do that a max of 3 times to get the answer.

The four consecutive integers are  

542, 543, 544, 545.

<em>good luck, hope this helps :)</em>
