Answer:

(8x + 1)° + ( 4x+11)° = 180° (linear pair )

8x +1 + 4x +11 = 180

8x + 4x + 1 + 11 = 180

12x + 12 = 180

12x = 180 - 12

12x = 168

x= 168/12

x = 14

= 6/110

= 3/55

Hence for every $55 revenue $3 out of it is the profit

27=3 raised to power (2x_1)

Ivahew [28]

Answer:

x = 2

Step-by-step explanation:

$27=3^{2x-1}\\\\3^{3}=3^{2x-1}\\$

Bases are equal. So, compare powers

2x - 1 = 3

Add 1 to both sides,

2x = 3+1

2x = 4

Divide both sides by 2

x = 4/2

x = 2
