Aidan drives to school and back each day. The school is 16 miles from his home. He averages 40 miles per hour on his way to scho

yarga [219]

Answer:

26 2/3 mph

Step-by-step explanation:

time = distance/speed

speed = distance/time

Use the first of these relations to find Aidan's time getting to school:

time = 16 mi/(40 mi/h) = 16/40 h = 0.4 h

Then the time Aidan takes to get home is 0.6 hours, and his average speed for that trip home is ...

speed = 16 mi/(0.6 h) = 26 2/3 mi/h

Rewrite the equation in Ax+By=C form Use the integers for A, B, and C <br><br><br>y=1/2x+6

Inessa05 [86]

The equation in required form is: -x+2y = 12

Step-by-step explanation:

Given equation is:

$y = \frac{1}{2}x+6$

In order to convert the equation in $Ax+By = C$

Multiplying both sides by 2

$2y = \frac{1}{2}x * 2 + 6*2\\2y = x + 12$

subtracting x from both sides

$2y-x = x-x+12\\2y-x = 12\\-x+2y = 12$

Hence,

The equation in required form is: -x+2y = 12
