Answer:
7
Step-by-step explanation:
assign the amount of weeks to x. then we write the equation 160+3x=195-2x which is 7
Answer:
(3x + 160) = (195 - 2x)
Step-by-step explanation:
Let Nick and Adam gain the weight for x weeks.
Nick's present weight = 160 pounds
Weight gain by Nick per week = 3 pounds
Weight gain in x weeks = 3x pounds
Total weight of Nick = (3x + 160)pounds
Similarly weight loss by Adam in x weeks = 2x pounds
Present weight of Adam = 195 pounds
Total weight of Adam after x weeks = (195 - 2x)pounds
Since Adam and Nick both have the same weight after x weeks therefore
(3x + 160) = (195 - 2x) will be the equation.
