Answer:
Step-by-step explanation:
No, because Bernie had to run 9 meters 7.77777778 time (70/9) and each of those 9-meter sections took 4 seconds, so her time was 31.1111111 (7.77777778*4). While Wendel had to run 61 meters 70-his headstart (9 meters) (70-9). So he only had to run 30.5 blocks of 2 meters (61/2). And since they're only 1 second long, it's 30.5*1=30.5.
So the answer is a NO because (Bernie) 31.1111111 seconds > 30.5 seconds (Wendel).

Answer: z =
<u>Step-by-step explanation:</u>
67a(t + z) = 45z + 67
67at + 67az = 45z + 67
<u>-67at -45z </u> <u>-45z -67at </u>
67az - 45z = 67 - 67at
z(67a - 45) = 67 - 67at
<u>÷ (67a - 45) </u> <u>÷ (67a - 45) </u>
z =
