Answer:

x = 7

Step-by-step explanation:

\frac{3}{7} x + 5 = 8

\frac{3}{7} x = 8-5

\frac{3}{7}  x = 3

x = 3 / \frac{3}{7}

x = 3 * \frac{7}{3} cancel 3

Then

x = 7

When using bits to represent fractions of a number, can you create all possible fractions?.
mafiozo [28]

Every rational number has a base-2 representation, but only the ones with denominators that are powers of 2 will require a finite number of bits to fully represent it.

For example,

\dfrac12 = 1\cdot2^{-1} = 0.1_2

\dfrac14 = 1\cdot2^{-2} = 0.01_2

\dfrac34 = \dfrac12 + \dfrac14 = 0.11_2

\dfrac{1023}{1024} = 1 - \dfrac1{2^{10}} = 1_2 - 0.0000000001_2 = 0.1111111111_2

whereas a number whose denominator contains anything else like 1/3 will need an infinite number of bits to represent it exactly.

\dfrac13 = \dfrac1{2^2} + \dfrac1{12} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{48} = \dfrac1{2^2} + \dfrac1{2^4} + \dfrac1{2^8} + \dfrac1{192}

and so on, so that it has a repeating but non-terminating base-2 representation

\dfrac13 = 0.010101\ldots_2

Answers for the 2 boxes please :)​
Ulleksa [173]

Step-by-step explanation:

2x - 3y = 25

+ (5x + 3y = 10)

=> 7x = 35, x = 5.

Therefore 2(5) - 3y = 25, 3y = -15, y = -5.

The solution pair is (5,-5).
