Jacob had math homework on 81 evenings.

Step-by-step explanation:

Time spent of each evening = 1/3 of an hour

Time spent in minutes =  \frac{1}{3}*60 = 20\ minutes

Total time spent = 27 hours

Total time spent in minutes = 27*60 = 1620 minutes

Let,

x be the number of evenings spent doing math homework.

Time spent each day* Number of evenings = Total time spent

20x=1620

Dividing both sides by 20

\frac{20x}{20}=\frac{1620}{20}\\x=81

Jacob had math homework on 81 evenings.

-18 = -6n - 6 + 2n Solve for n. ​
vodomira [7]

Answer:

n = 3

Step-by-step explanation:

-18 = -6n - 6 + 2n

-18 = -6n +2n -6 (Combine like terms)

-18= -4n -6

-18+6= -4n -6+6 (Addition Property of Equality)

-12 = -4n

-12/-4 = -4n/-4 (Division Property of Equality)

3=n

The value of 'n' is 3.

9x-3x-5=19 solve for x
Natasha_Volkova [10]

Answer: x=4

Step-by-step explanation:

Simplify the left side of 9x-3x-5=19 by combining like terms:

6x-5=19

Add 5 to both sides:

(6x-5)+5=19+5

Simplify:

6x=24

Divide both sides by 6:

(6x)/6=24/6

Simplify:

x=4
