Answer:
Step-by-step explanation:
Given that the equation x + y = z relates the whole numbers x, y, and z.
This implies x,y,z all three are whole numbers
Hence we get x+y =z
x = z-y
where y is a whole number
So y can be 0,1,2.....
From this we can say x can take at most the value z in case y =0 other wise x has to be less than z
So comparison of x,y,z would give

( the equality applying only when y =0)
This graph has no solutions and is inconsistent

for example (question 1),
3(2a - 5) you multiply the numbers inside the parenthesis ().
so it will be 6a - 15
And if there is a negative number in front of the parenthesis, you multiply that too
-1(2x-5) will be -2x+5
negative times negative will be positive!
The food with a higher unit price is chicken nuggets because when you multiply 7 and 25.90 you get 181.3. When you multiply 3 and 11.07 you get 33.21. The answer is chicken nuggets.
