which expression represents purely real numbers and which expression represents non-real complex number?​
Ray Of Light [21]

Incomplete question. However, I provided some explanation about non-real complex numbers.

<u>Explanation</u>:

In Mathematics, the term complex numbers (non-real complex numbers) in simple terms refers to numbers that containing an imaginary addition to it.

For example, the numbers 3i, 3 + 5i, 3i/4 are <u>non-real numbers</u> because of the addition of an imaginary part which is denoted by 'i'.

While real numbers, on the other hand, are numbers that do not include an imaginary part; they stand on their own, such as whole numbers 0, 1, 2, 3, etc, rational numbers like 3/4, etc.

(3x-4)/(14)=(9)/(10) Solve the proportion. Round to the tenths
____ [38]

The value of "x" is 5.5

<em><u>Solution:</u></em>

Given that we have to solve the proportion

\frac{3x - 4}{14} = \frac{9}{10}

We can solve the above given proportion for "x" by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable "x"

\rightarrow \frac{3x - 4}{14} = \frac{9}{10}\\\\\rightarrow 10(3x - 4) = 14 \times 9\\\\\rightarrow 30x - 40 = 126\\\\\rightarrow 30x = 126 + 40\\\\\rightarrow 30x = 166\\\\\rightarrow x = 5.533

On rounding to nearest tenth we get 5.5

Thus value of "x" is 5.5
