3 (6+3n) = 5n + 18 + 3n

amid [387]

Answer:

n = 0

Step-by-step explanation:

Multiply parenthesis by 3 and get:

1.) 18 + 9n = 5n + 18 + 3n

Then cancel the equal terms:

9n = 5n + 3n

Collect like terms:

9n = 8n

Move variable to the left:

9n - 8n = 0

n + 0

Plugin the value of 0 into x:

3 (6 + 3 x 0) = 18

5 x 0 + 3 x 0 + 18 = 18

*If the plugged in value have the same result than the answer is correct because 18 + 18.

Answer:

80%

Step-by-step explanation:

Please consider the complete question:

Micah is preparing for a piano recital. He practices for 50 minutes on Monday and 90 minutes on Wednesday. By how much did she increase the time she practiced each day?

We will use percent change formula to solve our given problem.

$\text{Percent change}=\frac{\text{Final value}-\text{Initial value}}{\text{Initial value}}\times 100\%$

Upon substituting our given values, we will get:

$\text{Percent change}=\frac{90-50}{50}\times 100\%$

$\text{Percent change}=\frac{40}{1}\times 2\%$

$\text{Percent change}=80\%$

Therefore, Micah had increased the time by 80%.
