Answer:

a = -3

Step-by-step explanation:

-2(a-3)=12

distribute the -2 to the terms in the paranthesis

-2a + 6 = 12

minus 6 both sides

-2a = 6

divide -2 both sides to isolate a

a = -3

I hope this was helpful (:

Answer: a=-3

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-2*(a-3)-(12)=0

(0 - 2 • (a - 3)) - 12 = 0

Pull out like factors :

-2a - 6 = -2 • (a + 3)

-2 = 0

A a non-zero constant never equals zero.

Solve : a+3 = 0

Subtract 3 from both sides of the equation :

a = -3

In AOPQ, mZO = (6x – 14)°, mZP = (2x + 16)°, and mZQ = (2x + 8)°. Find mZQ.

$\measuredangle Q=42$

Explanation

Step 1

the sum of the internal angles in a triangle equals 18o, so

$\begin{gathered} (2x+16)+(6x-14)+(2x+8)=180 \\ 2x+16+6x-14+2x+8=180 \\ \text{add similar terms} \\ 10x+10=180 \\ \text{subtract 10 in both sides} \\ 10x+10-10=180-10 \\ 10x=170 \\ \text{divide both sides by 10} \\ \frac{10x}{10}=\frac{170}{10} \\ x=17 \end{gathered}$

Step 2

now, replace the value of x in angle Q to find it
