6 plates with 3 spoons or 9 plates with 2 spoons
5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7
5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====
Use P to represent the number of purses that Aisha has. 1/2P x 3 if P= 12 then 1/2 (12) x 3= 18
(x+24)*3=186
x+24=186/3
x+24=62
x=38$ x-the price of the ticket
Answer:
Pattern seen is arithmetic progression. The both equations are same.
Step-by-step explanation:
a.The given pattern is 8,12,16,20,24....We can see that the difference between any two consecutive terms is 4.Therefore this is an AP(arithmetic progression).
b.Percy's equation , 
⇒
⇒
⇒
which is the same as Stella's equation . So , we can see that both equations are the same.
