Complete Question
A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20
Answer:
$7
Step-by-step explanation:
From the question we are told that :
Any 4 entrees = $20,
And there is a discount of $2 per entree.
Let us represent the original average cost of entrees as = a
Hence, we have the algebraic expression
4(a - 2) = 20
4a - 8 = 20
4a = 20 + 8
4a = 28
Divide both sides by 4
4a/4 = 28/4
a = 7
Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.

Answer:
Simplifying
Result: 18x - 12y
Step-by-step explanation:
I believe you simplify the expression, by using -2, the number outside the bracket, to multiply with the numbers within the bracket.
-2 x -9x = 18x
-2 x 6y = -12y
