(A)
(D)
Step-by-step explanation:
Given that:
Therefore, A and D are equivalent
Let you = y
Let your brother = b
y = 15
b = y + 3
Plug in 15 for y
b = 15 + 3
b = 18
Your brother picked up 18 shells.

In seven days they washed a total of 638.85 pounds of laundry. This means each day they washed about 91.26 pounds of laundry.
Answer:
1. D
2. y = 15.50x + 450
Step-by-step explanation:
1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.
2. x > (y - 450)/ 15.50
i) Rita gets paid $450 per week.
ii) She gets $15.50 for every new membership she sells.
iii) let y represent the total pay per week.
iv) let x represent the number of new memberships sold.
v) the equation representing total pay is y = 15.50x + 450.
vii) therefore the equation that represents a higher rate of membership sold is given by x > (y - 450)/ 15.50
