2 is less than or equal to w, and 9 is greater than or equal to w
use w only once in your inequality.
2 ≤ w ≤ 9
x is less than or equal to 7 and greater than 2
Use x only once in your inequality.
2 < x ≤ 7
4 is less than x and x is less than or equal to 8
use x only once in your inequality.
4 < x ≤ 8
A car travels at an average speed of 68 miles per hour. How many miles does it travel in 4 hour and 15 minutes
To calculate the distance traveled, we need to convert the 4 hours and 15 minutes into hours. Since there are 60 minutes in an hour, 15 minutes is equal to 15/60 = 0.25 hours.
Total time = 4 hours + 0.25 hours = 4.25 hours
Distance = speed × time
Distance = 68 mph × 4.25 hours
Distance = 289 miles
Therefore, the car travels 289 miles in 4 hours and 15 minutes.
A light bulb consumes 3150 watt-hours in 5 days and 6 hours. How many watt-hours does it consume per day?
To find the watt-hours consumed per day, we need to convert the 5 days and 6 hours into total hours.
Total time = (5 days × 24 hours/day) + 6 hours
Total time = 120 hours + 6 hours
Total time = 126 hours
Now, divide the total watt-hours consumed (3150 watt-hours) by the total number of hours.
Watt-hours per day = 3150 watt-hours ÷ 126 hours
Watt-hours per day ≈ 25 watt-hours
Therefore, the light bulb consumes approximately 25 watt-hours per day.
To write an inequality using "w" only once, you can use the logical connector "and" to combine the two given statements:
2 ≤ w ≤ 9
This inequality statement means that "w" is greater than or equal to 2 and less than or equal to 9.
