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

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

Use the conditional statement to answer the question.
lions [1.4K]
The original statement is true by the definition of what constitutes a right angle. It's simply set up this way. 

The contrapositive would be the statement "if the angle does not measure 90 degrees, then the angle is not a right angle" which is also a true statement. Example: a 37 degree angle is not a right angle.

Note: the original conditional "If P, then Q" would have the contrapositive be in the form "If not Q, then not P". We flip P and Q, and stick "not"s in front of both parts. 

So this is why the answer is choice D
