What does y equal y-16-3y=0
Afina-wow [57]

Answer:

y = - 8

Step-by-step explanation:

y - 16 - 3y = 0

Group like terms

y - 3y - 16 = 0

Add similar elements: y - 3y = - 2y

- 2y - 16 = 0

Add 16 to both sides

- 2y - 16 + 16 = 0 + 16

Simplify

- 2y = 16

Divide both sides by - 2

\frac{-2y}{-2} = \frac{16}{-2}

Simplify \frac{-2y}{-2}: y

\frac{-2y}{-2}

Apply the fraction rule: \frac{-a}{-b}  = \frac{a}{b}

= \frac{2y}{2}

Divide the numbers: \frac{2}{2}  = 1

= y

Simplify \frac{16}{-2}: - 8

\frac{16}{-2}

Apply the fraction rule: \frac{-a}{-b}  = \frac{a}{b}

-\frac{16}{2}

Divide the numbers: \frac{16}{2} = 8

= - 8

y = - 8

The area of the arrow given in the figure is 610 square cm

<h3>Area of composite figure</h3>

The given figure is made up of rectangle and triangle. The area is expressed as:

Area = Area of rectangle + area of triangle

Substitute the given parameters

Area of the arrow = (15*20) + 0.5(31 * 20)

Area of the arrow = 300 + 310
Area of the arrow = 610 square cm

Hence the area of the arrow given in the figure is 610 square cm
