9514 1404 393

Answer:

  • 1/3 hour per mile
  • 3 miles per hour

Step-by-step explanation:

Time per mile can be found by dividing hours by miles:

  (1/8 h)/(3/8 mi) = 1/3 h/mi

It will take him 1/3 hour to run 1 mile.

__

Miles per hour can be found by dividing miles by hours (or by finding the reciprocal of the above value):

  (3/8 mi)/(1/8 h) = 3/1 mi/h = 3 mi/h

He could run 3 miles in one hour.

Svetach [21]
Equations:

100 + 35m
50 + 35m

Steps:
100 + 35m = 50 + 35m <span>

<em>Set the equations equal to each other.</em>
</span>   <span />
<span>
100 + 35m = 50 + 35m <span>
-50              - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.

50+35m=35m
     -35m  -35m

<em>Subtract 35m from both sides of equation.</em>

50=m

In fifty months, they will have the same amount of money. They will each contain $1850 dollars.

Please help<br> if x = 3 and y=-4 find x2 + y2 and x2 -y2
lions [1.4K]
1. Plug in the 3 in all the x’s that are in the equation:

(3)2 + y2 = for x2 + y2

(3)2 - y2 = for x2 - y2

This would get you for both equations..

6 + y2 = for x2 + y2

6 - y2 = for x2 - y2

2. Now let’s plug in the value of y which is -4:

6 + (-4)2 = for x2 + y2

6 - (-4)2 = for x2 + y2

This would get you for both equations...

-2 = x2 + y2

14 = x2 - y2


Hope this helped, have an awesome day!
