Answer:
Plates are 2.80 Dollars and cups are 1.40 dollars
Step-by-step explanation:
Cups = c
Plates = p
6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80
7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00
Now use algebra to have the 30c be on one side and the rest on the other:
36p + 30c = 142.80 | -36p
30c = 142.80 - 36p
35p + 30c = 140.00 | -35p
30c = 140.00 - 35p
Now set them equal to each other about the 30c:
142.80 - 36p = 140.00 - 35p
Use algebra to solve for p:
142.80 - 36p = 140.00 - 35p | +36p
142.80 = 140.00 + p | - 140
2.80 = p
Go back to one of the "30c" equations and plug in the value for p:
30c = 140 - 35p
30c = 140 - 35(2.80)
30c = 140 - 98
30c = 42 | /30
c = 42/30
c = 1.4

Answer:
rub the magnets with a stronger magnet then they would be more magnetized
Explanation: If you rub a magnet with lets say some metal then that metal would be magnetized so if you where to rub those 2 magnets with a stronger magnet those magnetized would be magnetized even more than they already are
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
