If the reciprocal of 3 / 3 of a and 2a-9 of 3 are opposite to each other, then the value of a is () A. 3 / 2 b. - 3 / 2 C.3 D.2

If the reciprocal of 3 / 3 of a and 2a-9 of 3 are opposite to each other, then the value of a is () A. 3 / 2 b. - 3 / 2 C.3 D.2

C. A = - (2a-9), a = 3

If the reciprocal of 3 / A and 2a-9 / 3 are opposite, then a = ()

The reciprocal of 3 / A is opposite to 2a-9 / 3
Then a / 3 + (2a-9) / 3 = 0
(3a-9)/3=0
a-3=0
a=3

It is known that the opposite number of a is 3 / 2, and the reciprocal of B is - 2.5?

The opposite of a is 3 / 2, a = - 3 / 2
The reciprocal of B is - 2.5, B = - 2 / 5
2+5b(=-2)/2a(=-3)-5b(=-2)
2+2/3+2
=4+2/3
=14/3

The difference between 1 and the reciprocal of a number is five sixths, which is () or ()

The reciprocal of this number = 1 + 5 / 6 = 11 / 6 or = 1-5 / 6 = 1 / 6
So, this number is 6 / 11, or 6

The reciprocal of one number is 1.8 and the other is five sixths. What is the sum of these two numbers?

25 out of 18

The difference between a number and its reciprocal is 1 / 4. What is the number

Let X be the number
x-1/x=1/4
4x²-4=x
4x²-x-4=0
x=(1±√17）/8
So this number is (1 ± √ 17) / 8

If the difference between the reciprocal of 1 minus (1-x) and the reciprocal of (x-1) are opposite, then x =

-1

The inverse of the reciprocal of the smallest root of the equation x ^ - 3 | x | - 2 = 0

X^-3|x|-2=0
When x > 0
x^2-3x-2=0
Solution
X = (3 + √ 21) / 2 x = (3 - √ 21) / 2 (rounding off)
When x

The difference between the reciprocal of x minus - 2 is twice that of X

1/x-(-2)=2x

If 7x-3 and 1 / 3 are reciprocal, what is x?

7x-3=3
7x=6
x=6/7
