The product of 12 and the sum of a number and negative 3 is 12(x - 3)
<h3>How to represent algebraic expression?</h3>
An algebraic expression is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, multiplication etc.).
In other words, an algebraic expression is a mathematical statement that contains a combination of numbers, symbols, variables and mathematical operators.
Therefore, the product of 12 and the sum of a number and negative 3 is as follows:
let
the number = x
Hence,
12 × (x + (-3))
12 × (x - 3) = 12(x - 3)

Answer:
The sold 354.5 hamburgers and 300.5 cheeseburgers.
Step-by-step explanation:
Let number of hamburgers=h
Let number of cheeseburgers=c
On Sunday, the shop sold a combined total of 659 hamburgers and cheeseburgers. Therefore:
h+c=659....(I)
There were 50 fewer cheeseburgers sold than hamburgers .
c=h-50.....(ii)
Substitution of equation (ii) into (I)
h+(h-50)=659
2h=659+50
2h=709
h=709/2=354.5
From (ii)
c=h-50
=354.5-50=300.5
The sold 354.5 hamburgers and 300.5 cheeseburgers.
NOTE: These result are from the given data. However, we were not informed if the shop sells half burgers or not
2/3= 0.6
3.06 would be the answer I believe.
Hope this Helps!!
