Half the difference of 18 and a number n is equal to the sum of n and three. what is the value of n?

Answers

Answer 1

Answer:

n=12

Explanation:

First you have to write out the equation for the problem.

(18+n)/2=n+3

To get rid of the fraction, multiply both sides by 2.

18+n=2n+6

Now subtract n and subtract 6 from both sides and you will have your answer.

12=n

Answer 2

Answer:

n=4

Explanation:

(18-n)/2=n+3

2*((18-n)/2)=(n+3)*2

18-n=2n+6

  +n  +n

18    = 3n+6

-6             -6

12     =3n

÷3      ÷3

4=n

n=4

Answers

Answer:

[tex]\boxed{a=4}[/tex]

Explanation:

Part 1. Finding product of [tex](4a^2)(4^3)[/tex]

Step 1. [tex]4^3=64[/tex]

Step 2. [tex](4a^2) * (64) = (64 * 4)(a^2)[/tex]

Step 3. [tex](64 * 4)(a^2) = 256a^2[/tex]

[tex]\boxed{(4a^{2})(4^3) = 256a^{2}}[/tex]

Part 2. Simplifying the equation & solving for a

Step 1. [tex]\sqrt{256a^{2}} = \sqrt{64^{2}}[/tex] ⇒ [tex]16a = 64[/tex]

Step 2. [tex]\frac{16a}{16} = \frac{64}{16}[/tex]   (divide both sides by coefficient of variable)

[tex]\boxed{a = 4}[/tex]
