Hello!

Answer: ⇒⇒⇒⇒⇒⇒⇒ =54

_________________________________________________________________

Step-by-step explanation:

First you had to convert element to fraction.

$\frac{2}{3}*\frac{81}{1}$

Then you had to cross out by the common factor of 3.

$\frac{2}{1}=\frac{27}{1}$

Multiply by the fraction.

$\frac{2*27}{1*1}$

Multiply by the number.

$2*27=54$

$=\frac{54}{1*1}$

Again multiply by the number.

$1*1=1$

$=\frac{54}{1}$

Apply rule.

$\frac{54}{1}=54$

54 is the right answer.

Answer:

A. y = $\frac{-2}{3}x$ + 3

Explanation:

slope: $\frac{y2-y1}{x2-x1}$

: $\frac{1-3}{3-0}$

: $\frac{-2}{3}$

equation: y - y1 = m( x - x1 )

y - 1 = $\frac{-2}{3}$ ( x - 3 )

y = $\frac{-2}{3}x$ + 3

60°

Step-by-step explanation:

An exterior angle of a triangle is equal to the sum of the 2 interior opposite angles.

let the other interior angle be x, the

x + 50 = 110 ( subtract 50 from both sides )

x = 60

Thus the other interior opposite angle is 60°
