Answer:
At 8:52:30 am they will be side-by-side again
Step-by-step explanation:
Let s be the distance ran in one 1 lap.
Here Jeff runs one extra lap compared to Mandy for coming side by side again.
Mandy runs one lap in 2 minutes and 30 seconds = 150 s
Speed of Mandy,
Jeff runs one lap in 2 minutes and 15 seconds = 135 s
Speed of Jeff,
Let t be the time when Jeff run one extra lap,
That is
So after 1350 seconds Jeff comes side by side to Mandy,
They both start at 8:30 am
1350 s = 22.5 minutes = 22 minutes 30 seconds
Time = 8:52:30 am
the number number will be even
Common difference is 8
an = a1 + d(n-1)
a15 = 1 + 8(15-1)
a15 = 1+ 8*14
a15 = 1 +112
a15 =113
double it 226
even number
Answer:
9
Step-by-step explanation:
3x-16=2x-7. Add 16 to both sides to get 3x=2x+9. Then subtract 2x on both sides to get x=9
20. Bc when u solve, you should get x +47=8
Answer
