Y represents the total amount of money made over the weekend
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:
c
d
Step-by-step explanation:
Let f= number of five cent stamps
let t=number of ten cent stamps
total spent is 5f+10t=100
total stamps bought is f+t=13
5f+10t=100
f+t=13
f=13-t
5(13-t)+10t=100
65-5t+10t=100
5t=35
t=7
f+t=13
f+7=13
f=6
6 five cent stamps and 7 ten cent stamps
