Answer:

x = 35

Step-by-step explanation:

Co interior angle sum to 180° , so

x + 30 + 3x + 10 = 180 , that is

4x + 40 = 180 ( subtract 40 from both sides )

4x = 140 ( divide both sides by 4 )

x = 35

Find the quotient. Simplify if possible -6/10 + (-5/7)

Zepler [3.9K]

Answer: The correct answer is $\frac{21}{25}$

Step-by-step explanation:

To find a quotient, we need to divide the two numbers. The equation given to us is :

$\frac{-6}{10}\div \frac{-5}{7}$

To Simplify the above equation and finding out the quotient, we need to divide the above equation, we get:

$\Rightarrow \left(\frac{\frac{-6}{10}}{\frac{-5}{7}}\right)$

Taking the reciprocal of the denominator and multiplying it with the numerator, we get:

$\Rightarrow \frac{-6}{10}\times \frac{7}{-5}\\\\\Rightarrow \frac{42}{50}\\\\\Rightarrow \frac{21}{25}$

Hence, the correct answer is $\frac{21}{25}$
