Answer:
Step-by-step explanation:
2x - y = 8
<u> x + y = - 2 </u>
3x = 6
3x /3 = 6/3 Dividing bot sides by 3 to find x.
x = 2
Plug in the value of x to find y.
2 ( 2) - y = 8
4 - y = 8
-y = 8 - 4
- y = 4
y = -4
The solution: ( 2, -4)

The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs
<h3>Equation</h3>
- Total attendance = 75 people
- Cookies in each pack = 12
- Brownies in each pack = 15
- Number of cookies pack = c
- Number of brownies pack = b
15b + 12c = 75
If 1 package of brownies is bought
15b + 12c = 75
15(1) + 12c = 75
15 + 12c = 75
12c = 75 - 15
12c = 60
c = 60/12
c = 5 packs
- It is a reasonable value in this context
If 9 packages of brownies are bought
15b + 12c = 75
15(9) + 12c = 75
135 + 12c = 75
12c = 75 - 135
12c = -60
c = -60/12
c = -5 packs
- The value is not reasonable in this context

Answer: the answer is when the wheel is at 70.43° after 7.82seconds from when you ride on it
Step-by-step explanation:
Rule of 3
65ft center meaning the top point at 90° will be at 115ft since the diameter of the wheel is 50ft
If the 90° gets you at 115ft, at what degree will you reach 90ft?
90°----115ft
X°------90ft
(90x90) ÷ 115 = 70.43°
Then if 360° takes 40seconds which is the complete turn
360°----40s
70.43°--X
(70.43 x 40) ÷ 360 = 7.82s
