Answer:
x = 1/2 or x = -4
Step-by-step explanation:
Since the product equals zero, use the zero product rule.
(2x - 1)(x + 4) = 0
2x - 1 = 0 or x + 4 = 0
2x = 1 or x = -4
x = 1/2 or x = -4
Answer:
5 3/4
Step-by-step explanation:
Because 3/8 is less
Part A:
60/3= 20
You travel 1 mile every 20 minutes.
So, 5 minutes is 1/4 of 20.
Your friend walked 1/4 of a mile.
Part B:
You already know that your friend was 1/4 mile ahead of you.
She will continue to walk at the same rate.
You will walk:
6/4= 15
1 mile every 15 minutes.
Every 5 minutes, you walk a 1/3 of a mile.
(this is distance walking every 5 minutes)
Friend/ You
1/4 0
2/4 1/3
3/4 2/3
4/4 3/3
4/4= 1 and 3/3
Your friend will have walked 20 minutes before you caught up with her.
I hope this helps!
