Answer:
*a general admission ticket is $160
*a grandstand ticket is $390
Explanation: make 2 equations from the provided information
**g is a grandstand ticket and a is a general admission ticket.
4g+2a=1880, 4g+4a=2200
Steps: 4g+2a=1880 changes to 4g=1880-2a because you move the 2a in order to solve for g.
You can substitute the 4g into 4g+4a=2200 to get 1880-2a+4a=2200 and simplify to get 1880+2a=2200. subtract 1880 from both sides and you get 2a=320. divide both sides by 2 to get a=160.
After that you can substitute the value for a into 4g+4a=2200 to get 4g+4(160)=2200. simplify to get 4g+640=2200. subtract 640 from both sides to get 4g=1,560. divide both sides by 4 to get g=390.
Hope this helped! :)
Answer:
30 =z
Step-by-step explanation:
-15 = z/-2
Multiply each side by -2 to isolate z
-2 * -15 = z/ -2 * -2
30 =z
Given:
must correctly answer 80% of the questions
correctly answered questions = 26
incorrectly answered questions = 4
unanswered questions = 15
Total questions = 26 + 4 + 15 = 45
45 * 80% = 36 required correctly answered questions.
36 - 26 = 10
Out of 15 remaining questions, 10 questions must be correctly answered for Heidi to advance to the next level.
Answer:
The correct option is 1.
Step-by-step explanation:
In a graph, the lowest points of the functions are called local minima and highest points of the functions are called local maxima.
The point of local maxima and local minima can be more than one point. The graph must be continuous at extreme points.
From the given graph it is noticed that the highest point of the function is (0,1), therefore the local maxima is (0,1).
The lowest points of the graph are
But the graph is discontinuous at 
. So, the point is not a local minima.
The point of local minima are 
.
Therefore option 1 is correct.
