Answer:
175 adults
360 senior citizens
Step-by-step explanation:
Let x be the number of senior citizens
There were a total of 535 people, so
(535-x)=total number of adults
Total receipts=$8,355
Adult payments+Senior payments=$8,355
21(535-x)+13x=$8,355
$11,235-21x+13x=$8,355
$11,235-8x=$8,355
-8x=$-2,880
x=360 senior citizens
Number of adults=535-360=175 adults
To check, just substitute...
21(175)+13(360)
3,675+4,680
Which equals.....
$8,355
AB = BC, so 3x-2 = 2x+4. Also, BC = CA, so 2x+4=x+10.
Solve this system of linear equations:
3x-2 = 2x+4
2x+4=x+10 => x=6
Check: Does AB=BC? Does AB=BC?
Does 3(6)-2 = 2(6)+4? Does 16=16? YES.
Does BC = CA? Does 2(6)+4 = 6+10? YES
x = 6 (answer)
The range is which y are possible. So find all y coordinates of the points.
(8, 6, 5, 3, 2, 1)
Hope this helps.
The answer is 8x I believe
Answer:
It would be -81²x+81x-18= -9x+6
Step-by-step explanation:
When you work equation one you get 18. Then when you work equation two, you get -2/3=-0.666666667
