Marina CMI [18]

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.

6. What is an equation of the line that passes through the point (6,8)

Maru [420]

Answer:

x = 6

Step-by-step explanation:

y = 3 is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 3

A line perpendicular to this will be a vertical line parallel to the y- axis with equation

x = c ( c is the value of the x- coordinates the line passes through )

the line passes through (6, 8 ) with x- coordinate 6 , then

x = 6 ← equation of perpendicular line
