Answer:

m∠w = 131°

Step-by-step explanation:

Step 1: Find m∠zwy (Using sum of interior angles of a triangle)

m∠zwy = 180 - (46 + 85)

m∠zwy = 49°

Step 2: Find exterior angle (using Definition of Supplementary Angles)

m∠w = 180 - 49

m∠w = 131°

$y + 9 = 9 | - 9 \\ y+ 9 - 9 = 9 - 9 \\ y = 0$

$10 + 2x = 20 | - 10 \\ 10 + 2x - 10 = 20 - 10 \\ 2x = 10 | \div 2 \\ 2x \div 2 = 10 \div 2 \\ x = 5$

$17 + 3c = 26 | - 17 \\ 17 + 3c - 17 = 26 - 17 \\ 3c = 9 | \div 3 \\ 3c \div 3 = 9 \div 3 \\ c = 3$

$x - 4 = 3 | + 4 \\ x - 4 + 4 = 3 + 4 \\ x = 7$

$2z - 7 = 7 | + 7 \\ 2z - 7 + 7 = 7 + 7 \\ 2z = 14 | \div 2 \\ 2z \div 2 = 14 \div 2 \\ z = 7$

Constant of proportionality is 4

equation: x/y = 4

explanation:
let's take 20 and 5 for example, if you divide 20 by 5, you will 4 of course. that's the proportionality for the first one. if you continue to divide x value by y value you will get 4. for the last two you would divide 28 by 4 and multiply 8 by 4.

vesna_86 [32]

Answer: 1,208 seats

Step-by-step explanation:

39-18= 21

18 x 478 = 8,604

21 x 292 = 6,132

8,604 + 6,132 = 14,736

14,736 - 13,528 = 1,208
