3 0

Answer:

Step-by-step explanation:

The reason the answer would be 0 is because there is 20 students in all

This equation tells us that 14 students ate pizza and 6 ate burgers

Therefore we would add 14 + 6 to see how many students that is

In this case that is 20 students

If there is only 20 students in the lunchroom then you couldn't add anymore students

So, your answer is 0 students brought lunch from home

Hope this helps!

The sum of three consecutive even integers is -78, what are the integers ?

Digiron [165]

First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
1. You have that the sum of three consecutive even integers is $-78$ , therefore, you can given the variable $x
$ to the first integer, the second even integer is $x+2$ and the third one is $x+4
$ .
2. Calculate x:
 $x+(x+2)+(x+4)=-78$ 
 $3x+6=-78$
 $x=-28
$ 
 $x+2=-28+2=-26
$ 
 $x+4=-28+4=-24
$ 
Therefore, the answer is: $-28,-26,-24
