The mean can be found by adding the two numbers and dividing by 2
let the second number be y
(x + y)/2 = 1/2x + 1
solve for y
multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2
ANSWER: the second number is 2

655 rounded to the nearest hundred would be 700, so that could be an answer but some teachers say that you still have to keep the other digits. So it could be 700 or 1,766,700
B because it is (2x)(2x) which is equal to 4x^2
the answer is 3000 pounds.
Step-by-step explanation:
