number.

Answer:
2/3
Step-by-step explanation:
Let x represent the number. Then its reciprocal (the reciprocal of the original number) is 1/x
1/2 + 1/x . . . . . 1/2 added to the reciprocal of a number
2/x -1 . . . . . . . 1 less than twice the reciprocal of the original number
We want these expressions to be equal:

The original number is 2/3.
Answer:
n = 1
Step-by-step explanation:
Represent the number with n.
Then: reciprocal of this numer is 1/n.
1/2 added to this reciprocal comes to 1/n + 1/2, and this is equal to
2(1/n) - 1.
We must simplify this equation and solve for n:
Use the LCD 2n:
2 + n = 4 - 1, or 2 + n = 3, or n = 1.

Answer: (v + 7)(v -3)
Step-by-step explanation:
(v +7)(v -3)
v x v = v^2
v x -3 = -3v
7 x v = 7v
7 x -3 = -21
v^2 -3v +7v -21 = v^2 +4v -21 = 0
1+1+1+1×1×1+1+1+1+1+1+1+1+×1×1×1+1+1+1 = 14
They both have 5 in common
if you were to reduce the fraction it would be 11/16 because
55 divided by 5 is 11 and 80 divided by 5 is 16
