The penny size of a nail indicates the length of the nail. the penny size d is given by the literal equation d=4n−2, where n is the length (in inches) of the nail. a. solve the equation for n. n= question 2 b. use the equation from part (a) to find the lengths of nails with the following penny sizes: 3, 6, and 10. a 3-penny nail is inches. a 6-penny nail is inches. a 10-penny nail is inches.

The penny size d is given by the literal equation

Where n is the length (in inches) of the nail.

We can deduce the value of n from equation above:

Now we have to find n with various values of d.

1. when d = 3 inches

n = 1.25 inches

2. when d = 6 inches

n = 2 inches

3. when d = 10 inches

n = 3 inches

answer: -8.2562234e+13

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
