Answer:

\displaystyle{ -  \frac{9}{6} + ( -  \frac{3}{5} ) }

\displaystyle{ -  \frac{9}{6} -  \frac{3}{5}  }

  • Multiply the numerator and denominator to make it equivalent:

\displaystyle{ =  -  \frac{9}{6}  =  -  \frac{9 \times 5}{6 \times 5}  =  -  \frac{45}{30} }

\displaystyle{ =  \frac{3}{5}  =  \frac{3 \times 6}{5 \times 6}  =  \frac{18}{30} }

So,

\displaystyle{ =  -  \frac{45}{30}   -  \frac{18}{30}  = -   \frac{45 - 18}{30} =  -  \frac{37}{30}  }

Can someone help me with this ONE question? Write an equation.. and solve for X
matrenka [14]

Answer:

Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

x=17

Step-by-step explanation:

A 6 sided polygon is 720° degrees

so

720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)

Simplify

720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)

Combine like terms:

720=26x+278

flip equation:

26x+278=720

subtract 278 from both sides

26x=442

divide by 26 both sides:

x=17

Hope this helps.
