The price of a game that's been discounted 18% off its list price (x) = 0.18x
The price of a toy that sells for 18% more than the amount (x) needed to build the toy = 1.18x
The volume of water remaining in a tank after 3/10 of its original volume (x) is drained out = 7/10x
The total amount of flour in a bakery after receiving new stock equal to 3/10 if its current stock (x) = 13/10x
Answer:
for number 2:
(6cm x 4cm) + (6cm x 3cm)
24cm + 18cm + 12cm
2 x 54cm
108cm
for number 3:
80m + 1920m
2,000m
If none of the input value are repeated, it is a function.
The output value are y of (x) and the input value are x.You cannot have repeating x’s...U can have repeating y’s but not the x’s
For this case, the first thing we must do is define a variable.
We have then:
x: number of muffin plates
We now write the expression that models the problem.
We know there are 4 muffins in each dish, therefore, we have:

Substituting for x = 0 we have:
Answer:
There are 0 lemon muffins
d: 0
Answer: The correct option is (B) 
Step-by-step explanation: We are given the following system of equations :

We are to find the equation that could be the result of using substitution to solve the above system.
Substituting the value of x from equation (i) in equation (ii), we get

Thus, the required equation is 
Option (B) is CORRECT.
