Answer:
Step-by-step explanation:
x + 5/y^2
x = 2/3
y = 1/3
2/3 + 5 / (1/3)^2 Expand (1/3)^2
2/3 + 5 / (1/9) Put a 1 underneath the 5
2/3 + 5/1 / (1/9) Invert and multiply the second expression
2/3 + 5/1 * 9 Simplify 5/1
2/3 + 5* 9 Combine
45 2/3

Answer:
608
Step-by-step explanation:
The appropriate general formula here is a(n) = a(1) + (n -1)d, where d is the common difference. Here, d = +7. Thus:
a(92) = -29 + (92-1)(7) = 608
Answer:
The cost price of 12 boxes of pudding is $3.96
Step-by-step explanation:
Given as :
The quantity of pudding boxes = 3

<u>Using Unitary method</u>
∵ The cost price of 3 boxes of pudding = $0.99
or,The cost price of 1 boxes of pudding = 
= $0.33
∴The cost price of 12 boxes of pudding =$0.33 × 12
I.e x =$3.96
So,The cost price of 12 boxes of pudding = x =$3.96
Hence,The cost price of 12 boxes of pudding is $3.96 Answer
