Answer:
p = 5.50b
Step-by-step explanation:
2 beach balls cost 11
4 beach balls cost 22
6 beach balls cost 33
So each (1) ball b costs 5.50 ($) p

Step-by-step explanation:
Cameron task: 3/7 × 2/9
What he did:
• Simplify 3/7 to 1/7
• mulitiplied the fractions 1/7 and 2/9
Cameron's error was:
• The "simplification":
To simplify a fraction is to reduce to the lowest possible multiple. Illustration:
Simplify 16/100
= 2/25
But in the case of 3/7, the answer is 3/7.
What Cameron would have done:
1. 3/7 = 2/7 + 1/7
3/7 × 2/9 = (2/7 × 2/9) + (1/7 × 2/9)
= 4/63 + 2/63
= 6/63
2. since he simplified 3/7 to 1/7
1/7 = 3/7 × 1/3
Therefore,
3/7 × 2/9 = 1/7 × (2/9 × 3)
= 1/7 × 6/9
= 6/63
The graph represent a horizontal ellipse with center ,(h,k)=(-1,3)
Length of major axis, 2a =8-(-10) = 18
Therefore, a = 9
And length of minor axis, 2b =5-1 =4
Therefore b=2
The formula that we have to use to find the vertices
(h+-a,k)
(-1+-9,3) = (-1-9,3),(-1+9,3) = (-10,3),(8,3)
