Question

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs. If x represents the number of 3 lb weights and y represents the number of 10 lb weights, which equation can be used to find the number of each type of weight Bob has?

Answer 1

X10+2y=50 pounds this is your answers because if you do 3 times what number is less than 50 but still is even because all you have afterwars are 10 so 10 is 30. then 30 +?=50 its 20 so 10 multply by two plus 3 multiply by 10 equals 50. hope this helps!!!!!!!!!!

Answer 2

Answer:

            3 x + 10 y = 50

This is the equation which can be used to find the number of each type of weight Bob has.

Step-by-step explanation:

Bob has some 10 lb weights and some 3 lb weights. Together, all his weights add up to 50 lbs.

Let x represents the number of 3 lb weights and y represents the number of 10 lb weights

Total weight = 50 lb

Number of 3 lb weights = x

Number of 10 lb weights = y

Equating

            3 x + 10 y = 50

This is the equation which can be used to find the number of each type of weight Bob has.
