In this question ,it is given that
The penny size of a nail indicates the length of the nail. The penny size
d is given by the literal equation
where n is the length (in inches) of the nail.
In the first part we have to solve for n .
And for that firt we add 2 to both sides
Now we divide both sides by 4, that is
Part b.
When d=3
When d =6, we will get
When d =10, we will get
Divide 16 by 8.
16 ÷ 8 = 2.
So, one avocado costs $2.

Step-by-step explanation:
Answer:
x = 6 months.
The equation is given by $45 + ($49.45 × x) = ($56.95 × x).
Step-by-step explanation:
i) Let x be the number of months of Internet Service purchased till the Fast
Internet charges and Quick Internet charges become the same.
ii) Charges for Fast Internet for x months is given by $45 + ($49.45 × x)
iii) Charges for Quick Internet for x months is given by ($56.95 × x)
iv) According to the first statement we will now equate the equations in ii)
and iii) and solve for x.
Therefore, $45 + ($49.45 × x) = ($56.95 × x)
45 + 49.45 x = 56.95 x
Therefore (56.95 - 49.45) x = 45
7.50 × x = 45
Therefore x = 45 ÷ 7.5 = 6
