every number that is less than -1
Step-by-step explanation:
Yes
15+14 > 19 true
15+19 > 14 true
14+19 > 15 true
If all the statements are true then it’s a right triangle.
Since multiplying by 0.5 is the same as dividing by 2, the problem is described by the sentence
"Half the sum of a number and 40 equals 200"
From information given, we know
208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.
208 ÷ 65 = 3.2 hours
So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.
140 miles divided by 2.8 hours gives speed
140 ÷ 2.8 = 50 miles per hour
The number is seven because 7×7 = 49 and 49-3 = 46
