What is the solution of the equation? 17=2/3n+3

Answers

First, you should add -3 on both sides of the equation so you will have:
17 - 3 = 2/3n
14 = 2/3n
now you can multiply both sides by 3:
(14)3 = (2/3n)3
42 = 2n
42/2 = n
21 = n :)))

Answer: n = 24 for the expression 17=2/3n+3

Step by step explanation:

Step 1: simplify the equation

17 = 2/3n + 3

Solve the right hand side of the equation

17 - 3 = 2/3n

14 = 2/3n

Step 2: solve the remaining expression to get the value of n

14 * 3 n = 2

3n = 2/14

N = 1/7 * 3

N = 1/21

N= 21 (Since n is in the denominator)

a computer monitor is regularly priced at $320. during a two day sale the price was decreased to$240. which of the following is the percentage decrease of the monitors price during the sale?

Answers

In the question there are several information's worth taking note of. based on the given information's the required answer can be easily deduced. It is already given that the regular price of the computer monitor is $320. It is also given that during a two day sale the monitor price was decreased to $ 240. It is required to find the percentage decrease in the price of the monitor during the sale period.
Difference in price of the monitor = (320 - 240) dollars
      = 80 dollars.
Percentage of price decrease of the monitors = (80/320) * 100
   = 100/4
   = 25
So the price of the computer monitor was reduced by 25%.
