Answer:

u = 150

Step-by-step explanation:

Number of vertices:

Find the sum of the interior angles:

180(n - 2)

180(10 - 2)

180(8)

1440

To find u:

u = 1440 - (130 + 145 + 160 + 150 + 130 + 150 + 125 + 155 + 145)

u = 1440 - (1290)

u = 150

-3(y+3)=2y+3 what does y equal?

netineya [11]

[ Answer ]

Y = -12 / 5

[ Explanation ]

Expand:

-3y - 9 = 2y + 3

Add 9 to both sides:

-3y - 9 + 9 = 2y + 3 - 9

Simplify:

-3y = 2y + 12

Subtract 2y from both sides:

-3y - 2y = 2y + 12 - 2y

Simplify:

-5y = 12

Divide both sides by -5:

-5y / -5 = 12 / -5

Simplify:

Y = -12 / 5

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{6}{19} = \frac{x - 12}{2x - 2}$

Step 2: Solve for x

Cross-multiply: $\displaystyle 6(2x - 2) = 19(x - 12)$
Distribute: $\displaystyle 12x - 12 = 19x - 228$
Isolate x terms: $\displaystyle -12 = 7x - 228$
Isolate x term: $\displaystyle 216 = 7x$
Isolate x: $\displaystyle \frac{216}{7} = x$
Rewrite: $\displaystyle x = \frac{216}{7}$
