Answer:

40 miles an hour

Step-by-step explanation:

Note that the speed given to you is in 1/2 an hour. To get 1/2 hour to become 1 hour, multiply by 2.


20 = 1/2h

20(2) = (1/2)h(2)

Simplify. Isolate the h. What you do to one side, you do to the other

20(2) = h

h = 40

40 mph is your answer

MIDPOINT AND LINE LENGTH<br><br> WILL GIVE 70 MORE IF CORRECT
aleksandrvk [35]

Answer:

so midpoint formula is (x1+x2/2, y1+y2/2)

Step-by-step explanation:

so for 1: (11-11/2, 4+12/2)= (0,8)

then if you have the midpoint and one endpoint, find the distance between them to find the other endpoint.

so, for the third example, start with the x. how fair is -8 from -1? The answer is 7. So, we must ask, what number is 7 more than -1? Answer is 6. Then repeat for the y. 6 is 5 units away from 1, so then we do 1-5=-4. So it should be (6,-4) as point B
