Three consecutive even integers have a sum of -126. What is the smallest integer ?
SSSSS [86.1K]

Answer:

-40, - 42 and -44

Step-by-step explanation:

The fastes way here is trying. Lets pick a number, intelligently, and then work on it.

We need three even integers that sum -126. These will be all negative numbers and as they are consecutive they will be very similar (for example, -33 and -35 and -37). Thus, lets start by 1/3 of -126, which is -42:

(-42)+ (-44) + (-46) = - 132, so -42 no.

Lets go a step back: -40

(-40) + (-42) + (-44) = -126

So, the integers are -40, -42 and -44

Can somebody help me pleasee????
Marina86 [1]

Answer:

C

Step-by-step explanation:

3x + 3y = -x + 5y

3x + x = 5y - 3y

4x = 2y

Divide both by 2

2x = y

(1,2) when x=1, y=2

2(1)=2 is a true statement

(2,4) when x=2, y=4

2(2)=4 is a true statement
