Answer:
Maura runs at a pace of a 15 minute mile. Ava runs at a pace of a 16:40 minute mile. Maura runs faster.
Step-by-step explanation:
To get this answer I divided 1.25 by 5 which is .25. Then if you divide 60 minutes by .25 the answer is 15 minutes making her run at a pace of 15 minutes per mile. I did a similar calculation for Ava. I divided 50 by 3 which gave me 16.6667. Then i figured out what 2/3 of a minute was, which is 40 seconds. That led me to the conclusion that Ava runs at a pace of 16:40.
hope this helps!!
Answer:
They are vertical angles
x = 5
The mesure of the angles are 35, 35, 145, and 145
Step-by-step explanation:
vertical angles are derectly acrost from each other.
the equations 3x+20 and 10x-15, put into the equation 3x+20=10x-15 will solve for x.
20 = 10x − 15 − 3x
20 = 7x - 15
20 + 15 = 7x
35 = 7x
35/7 = x
5 = x
x = 5
The equations solved are 3 x 5 + 20 = 35 and 10 x 5 - 15 = 35
The sum of all the angles is 360, therefore 35 + 35 = 70
360 - 70 = 290
290/2 = 145
The last two angles are 145 degrees
