The sum of two times a number and 7 is five times the difference of a number and six. Solve for the variable then Round your answer to the nearest hundredths.

12.33

Step-by-step explanation:

let 'n' = a number

2n + 7 = 5(n - 6)

2n + 7 = 5n - 30

-3n = -37

n = 37/3 or 12.33

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
