Answer: -5 < x < 6. (-5, 6)
Step-by-step explanation:
To find the number of hours, divide the total distance by the speed.
Hours = 76 km / 14 km per hour
Hours = 4.529
Round the answer as needed.
For either one of the deals, just find what one card equals and times it by how many cards the other equation has.
e.g. 0.35 cents divide by 10 = 0.035. And now, you times it by 12 since the other deal is 12 cards for 40 cents.
0.035 x 12 = 0.48
So, 10 cards for 35 cents is not the better deal.
Let number of Adult ticket be x
and number of Child ticket be y
so
$282 = $24x + $18y.
:)
50 secs
as $90÷5hrs= 18 $ per hrs
$18÷60min=$0.30 per min
$0.30÷60sec=$0.005 per sec
$0.25÷$0.005= 50sec to make $0.25
so 50sec is the answer
