Answer:
You'd have to go step by step to get the actual value of y. Then solve the equations by inputting the value for y, therefore eliminating y from both equations
19*19 is 34 so I’m sure its 19
The range is a set of elements from the second set.
Therefore your answer is:
<h3>D. { -4, 1, 7, 15 }</h3>
First, convert the distance of a typical marathon to kilometers.
1 mi = 1.609 km
26.2 miles = 42.165 km
Divide this distance by Allan's average speed to get his average time.
42.165 km / 12 km/hr = 3.514 hours
