By working with the given linear equation we will see that:
a) n = (d + 2)/4
b)
- A 3-penny nail is_5/4_inches.
- A 6-penny nail is_2_inches.
- A 10-penny nail is_3_inches.
<h3>
How to solve the equation for n?</h3>
Here we have the linear equation:
d = 4n - 2
We want to solve it for n, it means that we need to isolate n in one side of the equation.
If we first add 2 in both sides of the equation, and then we divide both sides by 4, we will get:
d + 2 = 4n
(d + 2)/4 = n
That is the equation solved for n.
b) The penny size is d, and n is the length of the nail, then:
if d = 3, we have:
n = (3 + 2)/4 = 5/4
if d = 6, then:
n = (6 + 2)/4 = 2
if d = 10, then:
n = (10 + 2)/4 = 3
Thus:
- A 3-penny nail is_5/4_inches.
- A 6-penny nail is_2_inches.
- A 10-penny nail is_3_inches.

Answer:
Step-by-step explanation: subtract 6 from both sides and then divide both by -3
As in negative or positive It would be negative
We have to isolate x.
-7x + 35 = 20 - 7x
Add 7x to both sides.
35 = 20 + 0
35 = 20
This line is impossible to graph.
Answer:
54619.875 or 55,000
Step-by-step explanation:
5020 times 9.9 is 49698
1575 times 3.125 is 4921.875
49698 plus 4921.875 is 54619.875
