The product of two numbers is 240. The first number is 8 less than the second number. Which equation can be used to find x, the lesser number?

Step-by-step explanation:

We are given that is the lesser number.  Therefore, the larger number, which is 8 larger than , must be .  Our two numbers multiplied are , and they must be equal to 240, as that is given by the question.

Thus,

Equation:  

Distributive Property:  

Subtracting both sides by 240:  

Factoring:  

Casework:  

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

stops on an even number.
