Answer:
The equation that represents the relation is x = 3y - 5, where x is the number of plates and y is the number of cups
Explanation:
To solve this question chose a variable represents the number of the plates and another variable represents the number of the cups
Assume that the number of plates is x and the number of cups is y
∵ The number of plates = x
∵ The number of cups = y
∵ The number of plates is 5 less than 3 times the number of cups
→ That means x is less than 3 times y by 5
∵ 3 times y = 3 × y = 3y
∵ x is less than 3y by 5
→ Remember is means equal and "less" means subtract 5 from 3y
∴ x = 3y - 5
The equation that represents the relation is x = 3y - 5, where x is the number of plates and y is the number of cups
