Given:
total of 224 visitors
older than 18 paid $12
18 and below paid $8
total collection 2,520
Let l be visitors older than 18 and m be visitors 18 and below.
l + m = 224
12l + 8m = 2,520
l = 224 - m
12(224 - m) + 8m = 2520
2688 - 12m + 8m = 2520
-4m = 2520 - 2688
-4m = -168
m = -168/-4
m = 42 number of visitors 18 and below.
l = 224 - m
l = 224 - 42
l = 182 number of visitors older than 18.
12(182) + 8(42) = 2520
2184 + 336 = 2520
2520 = 2520

Step-by-step explanation:
Answer:
K = 8.3 repeating or 8 1/3
Step-by-step explanation:
3k - 5 = 20
Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )
3k/3 = k
25/3 = 8.3 repeating or 8 1/3
K = 8 1/3 or 8.3 repeating.
I believe x is 30 degrees.
The equilateral triangle has each angle equal to 60 degrees. So the small arc near x is also 60. The angle x is half the arc so would be 30.
This also makes sense because the triangle it forms with angle x and the center has center angle of 60 and angle formed by tangent and radius of 90. So it is a 30-60-90 triangle, making angle x 30.
