Upon formation of an equation from a given pattern, we know how the variables in the patter are related. Using the equation, we can find the value of one of the missing variables if the rest are known and also predict the values of the pattern at given conditions.
An example:
y = 2x + 5
if we are to predict the value of y at x = 3, we simply substitute 3 into x
y = 2(3) + 5
= 11
Answer:
Expression is:16n+2.50
For buying 4 tickets: 66.50
Step-by-step explanation:
You first have to set up the equation and each ticket cost 16 and you have to buy sixteen that is why it is 16n and then you have to pay 2.50 because you are buying online. Then you put four in for N because you are getting 4 tickets. Finally multiply 16 and 4 then add 2.50.

Just look for the one that have right adding
for president, we have 12 possible options
12_
Once we’ve decided on a president we only have 11 possible people to choose from for vice president
12_11

12•11= 132
So the answer is C.132
Answer:
angle 1 should equal to 54.
angle 2 should equal to 126.
Step-by-step explanation:
2x - 8 + 4x + 2 = 180
2x + 4x - 8 + 2 = 180
6x - 6 = 180
6x - 6 + 6 = 180 + 6
6x = 186
6x ÷ 6 = 186 ÷ 6
x = 31
---------------------------------------------
2x - 8 = A1
2(31) - 8 = A1
62 - 8 = A1
54 = A1
-----------------------------------------------
4x + 2 = A2
4(31) + 2 = A2
124 + 2 = A2
126 = A2
