11% = 16.5
1% = 16.5 / 11
= 1.5
100% = 1.5 * 100
= 150. His weight two years ago was 150 pounds.

X + (x * .11) = x + 16.5
2x * .11 = x + 16.5
Subtract x from both sides.
x * .11 = 16.5
Divide by .11 on both sides.
x = 150

Ray weighed 150 pounds two years ago.

ale4655 [162]

Answer:

2 pieces, 30ft each

Step-by-step explanation:

rope : 60ft long

we are trying to figure out how many equal pieces we can cut the rope into with the length of each piece to be the greatest possible integer:

if jason wants the length of rope to be the longest than the answer is 2, if he divides the length of 60 by 2, each piece will be 30 feet long. If he divides the rope by any number larger, each piece will be shorter than 30 feet, and he wants the piece to be the largest possible length.
