Answer:
$392. No they don't have enough money to pay for the trip.
They need $255 more dollars, which would take 14 weeks and 2 days.
Step-by-step explanation:
18 x 4 = 72
320 + 72 = 392
647 - 392 = 255
255/18 = 14.2
Answer: L=45, W=9
Step-by-step explanation:
Perimeter P=108 so if L=5W,
P=2(L+W)=2(5W+W)=2(6W)=12W
108=12W
W=108/12=9
L=5*9=45

Answer: After 16 seconds the boats will be traveling the same speed.
Step-by-step explanation:
Given: Mike is driving a boat at 12 mph and is increasing his speed by 0.2 mph each second.
Mike's spewed after x seconds = 12 + 0.2x
Hank is driving a boat at 26.4 mph and is decreasing his speed by 0.7 mph each second.
Hank's speed after x seconds = 26.4 -0.7 x
As per given,
12 + 0.2x = 26.4 -0.7 x
Subtract 12 from both sides
0.2x= 26.4-12-0.7x
⇒ 0.2x= 14.4-0.7x
Add 0.7xn on both sides , we get
0.2x+0.7x= 14.4
⇒ 0.9x = 14.4
Multiply 10 on both sides, we get
9x=144
Divide both sides by 9 , we get x= 16
Hence, after 16 seconds the boats will be traveling the same speed.
