Answer:
<h2> An angle is formed by the two rays.</h2>
Answer:
1.25 hours (Or 1 hour and 15 minutes) and 14 MPH
Step-by-step explanation:
1. If it takes 1 hour to travel 48 miles, then you can subtract it from the 60 miles, and have 12 miles left. Divide 12 by 48, and you get 0.25, so if you add it together, you get 1.25. To check, 48 x 1.25 equals 60.
2. 270 minutes is equal to 4.5 hours. Divide 63 by 4.5, and you'll get 14 miles per hour. To check, 4.5 x 14 equals 63.
Multiply the average by the number of tests to find the total of the scores:
82 x 3 = 246
88 x 3 = 264
The total of the three tests would need to be between 246 and 264
The total of the first two tests is 79 + 85 = 164
Subtract the total of the first two from the totals above:
246 - 164 = 82
264 - 164 = 100
The score of the third test needs to be between 82 and 100
Answer:
The number is 14
Step-by-step explanation:
Let n be the number. We can set up an equation:
2(n+20)=5n-2
Distribute the left side
2n+40=5n-2
Move like terms to one side. Note that the sign flips when we move a term from one side to the other.
40+2=5n-2n
42=3n
Divide both sides by 3
n=14
