Answer:
11.
Step-by-step explanation:
(2(n-3))-4=12
(2n-6)-4=12 <em>distribute</em>
2n-6-4=12
2n-10=12
2n=12+10 <em>isolate</em><em> </em><em>n</em><em> </em>
2n=22
2n÷2=22÷2
n=11

Answer:
<h2>1. 14 in</h2><h2>2. 28 in.</h2><h2>3. 43 in</h2>
Step-by-step explanation:
x 2x 3x + 1
|---------|-------------------|---------------------------|
|<-------------------- 85 in ------------------------>|
85 = x + 2x + 3x + 1
85 - 1 = 6x
x = 84 / 6
x = 14
1st piece = 14 in
2nd piece = 2(14) = 28 in
3rd piece = 3(14) + 1 = 43 in
----------------------------
total = 85 in
