Answer:
A. Jimmy lost the most weight at 26.25 lbs.
B. Jenny lost 12.5 lbs. Jimmy lost 26.25 lbs. Jerry lost 16 lbs.
Step-by-step explanation:
BTW-Jenny 125 pounds -Jimmy 175 pounds -Jerry 200 pounds
This is fairly simple, you just need to form the percentages into fractions so you can multiply the pounds of each person by their own respective fraction. Turning 10% into a fraction gives you 1/10, and then multiplying 125 by 1/10 gives you 12.5, the amount of weight that Jenny lost in lbs. Turning 15% into a fraction is a little more difficult but you can get it by turning it into 15/100 and finding the GCF, which would be 5 and you get 3/20. Then multiply that by 175 and you get 26.25, the amount that Jimmy lost in lbs. 8% is a little easier, just do what you did before. Turn into 8/100 and then into 2/25. Multiply that by 200 and you get 16, the amount that Jerry lost in lbs.
This is now correct
Hope this helped!

Answer:
<u><em>5x^3-7x^2-x+11</em></u>
Step-by-step explanation:
A = 7x^3-3x^2-6x+2
B = 2x^3+4x^2-5x-9
A-B = <u><em>5x^3-7x^2-x+11</em></u>

Answer:
solution: (2, -2)
Step-by-step explanation:
y = 7x - 16,
y = 2(2x - 5)
solving...
7x - 16 = 2*(2x - 5)
7x - 16 = 4x - 10
7x - 4x = 16 - 10
3x = 6
x = 2
y = 7*2 - 16 = 14 - 16 = -2
