Question

Answer:

A) 5 + 4x = 25
B) x = 5
C) It is not accurate but it is precise.
D) 17234 in
E) 300 seconds

For A, she spends 5 minutes stretching and walks 4 laps at unknown speed x. This gives us 5 + 4x. She spends a total of 25 minutes at the track, so we have
5+4x = 25

For B, we solve this by first subtracting 5 from both sides:
5 + 4x - 5 = 25 - 5
4x = 20

Now we divide both sides by 4:
4x/4 = 20/4
x = 5

For C, it is not accurate because the measurement it gives is not exactly 0.25 miles. It is precise, however, as it does not vary greatly.

For D, we first multiply 0.272 by 5280: 0.275(5280) = 1436.16 ft. Now we multiply by 12:
1436.16(12) = 17233.92 in ≈ 17234 in

For E, we take 5 minutes and multiply by 60:
5(60) = 300 seconds
