Saleh is delivering newspapers for his part-time job. He needs to deliver 30 newspapers and has distributed 10 so far.

Nikolay [14]

He has delivered 33.3% of his papers. Think of it as a fraction 10/30. Now 100% is 30 papers. 1/3 of that, which is our fraction reduced, is where you get 33.3%. If you divide 100 into thirds (100/3), you get the percent.

Solve P = 8/3 R + 30 for R.

vampirchik [111]

Answer:

R = (3P-30)/8

Step-by-step explanation:

subtract 30 from each side to get:

P-30 = $\frac{8}{3}$ R

multiply each side by $\frac{3}{8}$ to get:

$\frac{3}{8}$ · P - 30 = R

R = (3P-30)/8
