The answer is C 1.312, -1.33, -1 3/9, -1 3/10
X and y are the numbers
y>x
sum (addition) of twice a number (2x) and larger number (y) is (=) 145
2x+y=145
difference between them is 55 (y is bigger so it would be x is subtracted from y)
y-x=55
so the equations are
2x+y=145 and
y-x=55
we could add x to both sides in the 2nd equation to obtain
y=x+55, but that doesn't really represent that the difference is 55, though they are the same euation
so I would say C and D only
Answer: 8/16
Step-by-step explanation: Half of the numbers are odd, half of the others as even, so 8/16, which is half of the numbers.
