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:
The answer is b
Step-by-step explanation:
A is true because an outliner is a number that is much lesser or greater than the rest it creates a gap.
C is true because data must be sorted for all sorts of graphs to work.
D is true as line plots work by the amount of marks for each number of something. Therefore, the number of marks shows the size of the data.
Answer:
6 pictures
Step-by-step explanation:
Let x be the number of pictures that was bought
Let y be the total amount of money collected for the picture
y= 3.25+12.75
3.25+12.75x= 79.75
Therefore x can be calculated as follows
12.75x= 79.75-3.25
12.75x= 76.5
x= 76.5/12.75
= 6
Hence Joshua ordered 6 pictures
Answer:
1
Step-by-step explanation:
y2 - y1/x2 - x1
10 + 8/8 + 10 = 18/18 = 1
