Three consecutive even numbers whose sum is -42

-12, -14, -16

Step-by-step explanation:

x + (x+2) + (x+4) = -42

3x + 6 = -42

Isolate the variable 3x by subtracting 6 from both sides

3x = -48

Then isolate the variable x by dividing 3 from both sides

x = -16

Then add 2 for the 2nd number

Then add 4 for the third number

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
