12(2a-3)=-4a+5

Remember to follow PEMDAS. Note the equal sign, what you do to one side, you do to the other.

First, distribute 12 to all terms within the parenthesis

12(2a) = 24a

12(-3) = -36

24a - 36 = -4a + 5

Add 4a to both sides, and add 36 to both sides

24a (+4a) - 36 (+36) = -4a (+4a) + 5 (+36)

24a + 4a = 5 + 36

Simplify

28a = 41

Isolate the a. Divide 28 from both sides

28a/28 = 41/28

a = 41/28

Simplify a

a = 1.46 (simplified)

hope this helps

The diagram shows a sector of a circle radius 10cm
Yuki888 [10]

Answer:

\text{Perimeter of sector = 43.6 (Rounded to the nearest tenth.)}

Step-by-step explanation:

\text{Perimeter of the sector = Radius + arc length + radius}

\text{Radius = 10 cm}

\text{Perimeter of the sector = 10 + arc length + 10  }

 \text{Perimeter of the sector = 20 + arc length  }

\text{arc length   = (sector angle/ 360 ) * perimeter of the circle}

\text{Perimeter of a circle }=2\pi r

\text{sector angle} = 135

\text{arc length}   =  (135/ 360 ) * 2\pi (10)

= (3/8) 20\pi

= 15\pi /2

\text{Using  }\pi =3.14

= 15 * 3.14 /2

= 23.55

\text{Perimeter of the sector = 20  + 23.55}

= 43.55

= 43.6  cm

\text{perimeter of the sector  = 43.6  cm }
