2/3*n-4 = 2*n

subtract 2/3 n from each side

-4 = 2n - 2/3 n

-4 = 6/3 n - 2/3 n

-4 = 4/3 n

multiply by 3/4 on each side

-4 * 3/4 = n

-3 = n

The number is -3

Answer:

n = -3

Step-by-step explanation:

Let the number be n. Then (2/3)n-4 = 2n.

Solve for n. To accomplish this, start by mult. both sides by 3, to remove the fractional coefficient: 2n - 12 = 6 n, or -12 = 4n. then n = -3 (answer)

To complete a task in 15 days a company needs 4 people each working for 8 hours per day. the company decides to have 5 people ea

Lilit [14]

It would take 16 days
explanation
if it takes 15 for 4 people to work 8 hours to complete the task, it would be a total of 480 hours. I multiplied 15x4x8. i multiplied 5x6 to get 30. I have to find the third value so i divided 30 from 480 to get 16.

Hannah went on a bike ride on Saturday and Sunday every weekend in November. She recorded the number of miles she rode each time

geniusboy [140]

Looking at the line plot, the longest number of miles is 50, and the shortest is 48 1/4.

Calculating the difference, we have:

$\begin{gathered} 50-48\frac{1}{4} \\ =50-(48+\frac{1}{4}) \\ =50-48-\frac{1}{4} \\ =2-\frac{1}{4} \\ =\frac{8}{4}-\frac{1}{4} \\ =\frac{7}{4} \\ =1\frac{3}{4} \end{gathered}$

Therefore the correct option is the third one.
