Answer:

\pink{ - 1 \frac{7}{9} }

Step-by-step explanation:

( \frac{2}{5}  \div  \frac{3}{8} ) \div ( -  \frac{3}{5} ) \\ (\frac{2}{5}  \times  \frac{8}{3} ) \times ( -  \frac{5}{3} ) \\  \frac{16}{15}  \times  -  \frac{5}{3}  \\ -   \frac{80}{45}

As the answer can be more simplified, divide both numerator and denominator by 5.

-  \frac{16}{9}  =   - 1 \frac{7}{9}

Find the value of X ?
vredina [299]

Answer:

x = 19

Step-by-step explanation:

(10x - 23) and (7x + 34) are vertically opposite angles and congruent, so

10x - 23 = 7x + 34 (subtract 7x from both sides )

3x - 23 = 34 ( add 23 to both sides )

3x = 57 ( divide both sides by 3 )

x = 19
