Answer:
second one: -4x +6
third one: 4x - 16
fourth: 245x + 30
fifth: 81x - 21x
(last one) sixth: 1600x + 8x
( if this goes wrong then I did something else)
So in 30 min will hike 2 1/4 miles =9 of those 1/4 miles therefore in 10 min will hike 9/3 =3 of those 1/4 miles = 3/4 of a mile
3/4 mile in 10 min;
(3/4)• 4 = 3 miles in 40 min;
6 miles in 80 min;
9 miles in 120 min;
12 miles in 160 min;
15 miles in 200 min;
18 miles in 240 min or 4 hours
Answer:
Step-by-step explanation:
it means that
125-30 < u < 125+30 so
95 < u < 155
it gives ![]95,155[](https://tex.z-dn.net/?f=%5D95%2C155%5B)
Answer:
$7
because theres 4 quarters in a mile so one mile would equal to $2 bc
0.50 x 4 = $2
and you have to go 2 miles so
$2 + $2 = $4
then you add the the cost of the taxi so
$4+ $3
= $7
