The answer to your question is x=31

The total would be 180 degrees because angles on a straight line would always add up to 180.
(3x+31)+(2x-6)=180
5x+25=180
     -25   -25
5x=155
/5     /5
x=31

Find the ratio a:b, if 2a−b/6 = b/3
evablogger [386]

If 2a−b/6 = b/3, then ratio a:b = 3 : 2

<h3><u>Solution:</u></h3>

Given that 2a−b/6 = b/3

We have to find the ratio of a:b

In mathematics, a ratio indicates how many times one number contains another

A ratio between two or more quantities is a way of measuring their sizes compared to each other

let us first solve the given expression

\frac{2a -b}{6} = \frac{b}{3}

On cross multiplication we get,

6a - 3b = 6b

6a = 6b + 3b

6a = 9b

a = \frac{9b}{6}\\\\\frac{a}{b} = \frac{3}{2}

To convert a fraction to a ratio, first write down the numerator, or top number. Second, write a colon. Thirdly, write down the denominator, or bottom number

Therefore ratio a:b = 3 : 2
