Alvin weighed 200 pounds at the beginning of the semester. After eating healthy foods and exercising regularly for ten weeks, he lost 3 pounds per week. Which expression would he use to represent his current weight at any time after x amount of weeks if he continues to lose 3 pounds per week?
Alvin's current weight after x amount of weeks if he continues to lose 3 pounds per week can be represented by the expression: 200 - 3x.
If Alvin continues to lose 3 pounds per week, the expression he would use to represent his current weight at any time after x amount of weeks would be:
200 - (3 * x)
To find an expression to represent Alvin's current weight after x amount of weeks, we need to start with his initial weight of 200 pounds and subtract the weight he loses due to healthy eating and regular exercise.
Since Alvin loses 3 pounds per week, we can multiply the number of weeks (x) by the amount of weight lost per week (3) to find the total weight he has lost. This gives us a weight loss of 3x pounds.
To find Alvin's current weight after x weeks, we subtract the weight loss (3x) from his initial weight (200). The expression would be:
Current weight = 200 - 3x
Therefore, Alvin's current weight after x weeks, if he continues to lose 3 pounds per week, is given by the expression 200 - 3x.
