Answer:

x = 4

31x + 6 = 130

12x + 2 = 50

Step-by-step explanation:

two angles side by side are equal to 180.

(31x + 6) + (12x + 2) = 180

43x + 8 = 180

43x = 172

x = 4

31x + 6 = 124 + 4 = 130

12x + 2 = 48 + 2 = 50

A number written in fraction form whose numerator or denominator is itself a fraction is called a complex fraction.
pickupchik [31]
<h3>Answer:</h3>

"complex"

<h3>Explanation:</h3>

The sentence you're to complete is a direct copy of the sentence at the beginning of the problem statement. Match the words and identify the one corresponding to the blank.

_____

<em>Comment on the example</em>

"Copy and paste" does not always work well on Brainly, especially when the characters being copied are not text characters. Many fractions get mangled in the process.

We suspect you intend ...

(1/3)/(4/7) = (1/3) ÷ (4/7)

In typeset form, this might be ...

\displaystyle\frac{\left(\frac{1}{3}\right)}{\left(\frac{4}{7}\right)}

___

Please note that the symbols "/" and "÷" and the word "over" are generally taken to mean exactly the same thing.* When math operations are involved in numerators or denominators, generally you need to enclose those numerators and denominators in parentheses.

1/3÷4/7 = 1/(3·4·7) = 1/84

(1/3)÷(4/7) = (1/3)·(7/4) = 7/12

___

* Some web sites treat them differently. Sometimes "÷" is taken to mean "the quantity everything that comes before the symbol '÷' divided by the quantity everything that comes after the symbol". Sometimes the word "over" is intended to mean the same thing. This usage for ÷ and "over" is non-standard, so it is best to use parentheses to clarify intent.
