gulaghasi [49]

X + 1.5 â‰¤ 5 X â‰¤ 3.5 "Julia is allows to watch no more than 5 hours of television" X â‰¤ 5 "She has watched 1.5 hours" X + 1.5 â‰¤ 5 So the inequality to solve is: X + 1.5 â‰¤ 5 Now to solve it, just subtract 1.5 from both sides: X + 1.5 â‰¤ 5 X + 1.5 - 1.5 â‰¤ 5 - 1.5 X â‰¤ 3.5 So Julia can watch up to 3.5 more hours of TV this week.

A boat traveled 37 miles in 2 hours. At this rate, how many miles will the boat travel in

Inessa [10]

Answer:

i. The boat will travel 18.5 miles in one hour

ii. The boat will travel 9.25 miles in half an hour

iii. The boat will travel 27.75 miles in one and a half hours

Explanation:

We are given that the boat travel 37 miles in 2 hours

To get the miles traveled, we can simply use cross multiplication

i. Miles traveled by the boat in one hour:

37 miles .....................> 2 hours

x miles ........................> 1 hour

$x = \frac{37*1}{2}=18.5$ miles

ii. Miles traveled in half an hour:

37 miles .....................> 2 hours

x miles ........................> 0.5 hour

$x = \frac{37*0.5}{2}=9.25$ miles

iii. Miles traveled in an hour and a half:

37 miles .....................> 2 hours

x miles ........................> 1.5 hour

$x = \frac{37*1.5}{2}=27.75$ miles

Hope this helps :)
