Question

Let y be the number of children at a party and x be the number of pizzas served at the party. Which equation represents 3 pizzas for every 6 children? (choose 2)
Responses
A 3y = 6x3 y = 6 x
B y = 2xy = 2 x
C y = 3x – 6y = 3 x – 6
D y = 6x – 3y = 6 x – 3
E
y = 1 x

Table with 3 columns and 2 rows.Row 1: Column 1, 'y ='; Column 2, '1'; Column 3, 'x' Row 2: Column 1, '2'; Column 2, 'undefined'; Column 3, 'undefined'

Answer 1

A and B.

Reason: 3 pizzas per 6 children gives pizzas:children = 3:6 = 1:2, so x/y = 1/2 ⇒ x = (1/2)y ⇒ y = 2x. Option A (3y = 6x) simplifies to y = 2x, and B is y = 2x.
