We solve the as follows:

<span>1. Solve proportion 12/15 = 18/b
</span>( 12/15 = 18/b ) b<span>
( 12b/15 = 18 ) 15/12
b = 18(15/12)
b = 45/2

2. Solve equations 

A. -x + 4 = x +6 
</span>-x + 4 - x = x +6 - x
<span>-2x + 4 - 4 = 6 - 4
-2x = 2
x = -1

B. 5n + 7 =7(n+1) -2n 
5n + 7 = 7n + 7 - 2n
5n -7n + 2n = 7 - 7
0 = 0

C. -4(p+2) + 8 = 2(p-1) - 7p + 15
-4p - 8 + 8 = 2p - 2 - 7p + 15
-4p + 7p - 2p = -2 + 15 + 8 - 8
p =13

3. Solve a/b x - c = 0 for x 
</span>a/b x - c = 0 
( a/b x = c ) b/a
x = bc / a

Answer:

7.5

Step-by-step explanation:

SInce 11x-17 is a corrosponding angle to 65, we can make an equation with them.

11x-17=65

Carry over the 17 (add to both sides)

11x= 82

divide 82 by 11

x=7.5
