Answer:
n = m-a
Step-by-step explanation:
The formula is : ...(1)
a is actual cost of an item
m is original price
n is amount of coupon
We need to solve the formula for the amount of coupen.
Subtracting m to the both sides of equation (1).
a-m = m-n-m
-n=a-m
or
n = m-a
So, the formula for the amount of coupon is n = m-a.
Student Tickets - x-64
Adult Tickets - x
x+x-64=386
2x=450
x=225
225 adult tickets were sold,
161 student tickets were sold.
Hope that helps!
Answer
2
Step-by-step explanation:
(reorder terms)
<u>2x + 2x</u> = 8
collect like terms
<u>4x=8</u>
divide both sides of the equation
x = 2
This is a simple problem! So let’s start. The rule a negative and a negative makes a positive plays a role in here so then we can switch it to -6+9 now subtract 9 to 6 and you get 3. That will be your answer. You can switch the numbers around to make it easier that what I like to do. For example, instead of having -6+9 you could instead do 9-6!
Hope this helps!
