Answer:
The answer is given below
Step-by-step explanation:
Given that the parallelogram ABCD has m∠A = 79°
A parallelogram is a quadrilateral with two pairs of parallel lines. For a parallelogram, opposite sides of a parallelogram is equal and opposite angles are also equal. Also the diagonal of a quadrilateral bisect each other.
m∠C = m∠A = 79° (opposite angles of a parallelogram are congruent)
m∠C = 79°
m∠B + m∠A = 180° (consecutive angles of a parallelogram are supplementary)
m∠B + 79 = 180
m∠B = 180 - 79
m∠B = 101°
m∠B = m∠D = 101° (opposite angles of a parallelogram are congruent)
m∠D = 101°
This is basically a physics problem that requires you to know v=s/t. The question asks for the velocity of each racer and you are provided with how many laps they made (s) and the time it took them (t). Therefore it is just a matter of you calculating these.
35/84= 0,416666666666667
42/96.6= 0,434782608695652
38/102.6= 0,37037037037037
Now because we used laps as the unit for s, DO NOT PUT ANY unit of measurement after it. This is just a good way of comparing one to another.
As you can see the fastest of them all should then be Evans.
The answer is A.) 3x-7y and -7y+3x
This is due to "3x" implies the value is positive, or "+3x", and -7y remains -7y.
So, we have 3x-7y and -7y+3x.
I hope this helps!
