Question

The penny size of a nail indicates the length of the nail. The penny size d

Answer 1

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.

How to solve the equation for n?

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.
