Answer:

Step-by-step explanation:

so the first bit you don't even need its trying to trick you

first you do 72/6= 12 so that means for every 12 students, you need one tutor

then you do 120-72=48 and that means there are 48 students that have no tutor

to find out how much more tutors you need, do 48÷12= 4, meaning you need 4 extra tutors for the 48 more kids.

last you add 72 witch is the about of tutors you started with, to 4 witch is how much you just got.

72+4=76

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
