Answer:
(a)
(b)
(c)
Step-by-step explanation:
We are required to construct 3 linear equations starting with the given solution z = 1/3.
<u>Equation 1</u>
<u />
<u />
Multiply both sides by 9

Rewrite 3 as 5-2
9z=5-2
Add 2 to both sides
Our first equation is: 
<u>Equation 2</u>
<u />
<u />
Multiply both sides by 21

Rewrite 7 as 11-4
21z=11-4
Subtract 11 from both sides
Our second equation is: 
<u>Equation 3</u>
<u />
<u />
Multiply both sides by 6

Rewrite 6z as 4z+2z
4z+2z=2
Subtract 2z from both sides
Our third equation is: 
1 ft = 12 in
192/12 = 16
16 ft = 192 in
Answer:
look below!
Step-by-step explanation:
For the length I think you meant 32, and if you did it is $14.40
If not and you meant length of 2 it is $0.90
One way to find the GCF of a number is to list out all of the factors of each number and then find which factors they both have. The largest of the common factors is the GCF. Hope this helps!
