What is addition?
The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
A random sample of students was surveyed and asked to list their grade level and whether or not they have a pet.
The total number of pets is 48.
Let a number of a pet in 6th grade be x.
So, [tex]x + 12 + 19 = 48\\\\x = 48 -31\\\\x =17[/tex]
The number of no pets in 6th grade
17 + y = 30
y = 13
The number of no pets in 7th grade
12 + z = 23
z = 11
The total result of survey in 8th grade
30 + 23 + a = 90
a = 37
The number of no pets in 8th grade
19 + b = 37
b = 18
The total number of no pets would be 42.
