The sum of three consecutive even integers is –78. What are the integers?
Ivanshal [37]

Step-by-step explanation:

(Hope this explanation can ease your mind a little if possible! Alright let's go! :D)

Let n be the middle of the 3 consecutive even integers. Therefore, (n - 2) and (n + 2) are the smallest and largest of the 3 numbers respectively.

We know that (n - 2) + n + (n + 2) = 78,

so 3n = 78, and n = 78/3 = 26.

Since the middle number is 26, the smallest number is 26 - 2 = 24 and the largest number is 26 + 2 = 28.

Feel free to comment below if you have any queries!

What is y = 3/4x - 5/2 in standard form?
Lubov Fominskaja [6]
The eq'n of a str. line in std. form looks like Ax + By = C or Ax + By + D = 0.

Start by determining the LCD of <span>3/4x - 5/2; it is 4.

Multiply both terms on the right by 4.  This results in 4y = 3x - 10.

This last result can be re-written as 3x - 4y - 10 = 0 (the equation in std. form)</span>
