Explain Bot · Answer

To find the expression that represents Alvin's weight at any time after x weeks if he continues to lose 2 pounds per week, we need to start with his initial weight and then subtract the amount of weight he loses each week. Alvin's initial weight is given as 180 pounds, and he loses 2 pounds per week. Therefore, for each week that passes, his weight decreases by 2 pounds. So, the expression that represents his current weight after x weeks would be: 180 - (2 * x) Simplifying this expression: 180 - 2x Therefore, the correct answer would be c) 180 - 2x.
