Answer:
Quadrilateral ABCD is inscribed in a circle, then
A + C = 180
=> 2x + 9 + 3x + 1 = 180
=> 5x = 170
=> x = 34
=> A = 2 x 34 + 9 = 77 deg
Hope this helps!

As the input goes up by 3, the output goes down by 1.
Answer:
7n = 12+ 3n
Step-by-step explanation:
The first thing to do is subtract 3n from 7n. This would get you 4n = 12. 4 times 3 equals 12, so n equals 3.
To check your answer. 21 = 12+9. sure enough it matches our answer
1. 1650 / 55 = 330 / 11 = 30
2. 5634 / 18 = 939 / 3 = 313
3. 6440 / 28 = 920 / 4 = 230
4. 5256 / 52 = 2628 / 26 = 1314 / 13 = 101.07
5. 1955 / 85 = 391 / 17 = 23
Answer:
Step-by-step explanation:
Given
<em>(You and 3 friends)</em>
per individual
Required
Determine the change
First, we need to determine the total amount spent on movie ticket.
The question does not state whether I pay for my friend's ticket.
So, we'll work on what is obvious.
i.e
Add this amount to the amount spent on popcorn
To get the Change, we have to deduct the total amount spent from the amount given by mom
Hence:
The change is $10.25
