The first answer is c. The second is b
I'm assuming you mean to say that the clock already showed 10 seconds when she started the race.
It took her 5 seconds to run 100 meters since 15-10 = 5.
To find her speed, divide 100 over 5 to get 100/5 = 20 meters per second
20 meters per second is approximately equal to 44.7387258 miles per hour.
Something seems really off because the fastest record speed for a human runner was around 28 mph. Though of course, this is just a hypothetical math problem.

Answer:
f(x) = 2x – 3
f(0) = 2(0) – 3 = -3
f(1) = 2(1) – 3 = 2 – 3 = -1
(f(0) + f(1))/2 = (-3 - 1)/2 = -4/2 (f(0) + f(1))/2 = - 2
Okay so three outfits of shirt and shorts would be 3 shirts and 3 shorts.
each shirt is $10 so 3 x 10 is 30
64.50-30 is 34.5
divide that by 3 (the 3 shorts)
34.50 / 3 = 11.5
each pair of shorts costs $11.50
hope this helps! give me brain lists please :)
