Answer:
There is no question.
Step-by-step explanation:
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
Simply simplify the ratios/fractions into their simplest fraction form and divide the numerator by the denominator. If they are equal, they are in fact proportions, if not, they aren't
350(1+0.75)t (add the numbers)
350*1.75t (Calculate the product)
612.5 t
-1/4 is not = -1 / 1/4 ( its = -4) so its neither .
