Answer:
x=1
Step-by-step explanation:
For this problem, we can choose to eliminate either the x values or the y values.
In this case, it would be easier to do y.
We alter the first equation by multiplying by -2 on both sides.
-4x+-6y=-16
Now, we have the equations
-4x+-6y=-16 and 5x+6y=17.
We can see that there is -6y in one equation and 6y in the other, meaning that if we add both equations together, the ys will cancel each other out because they are opposites.
So let's add the equations.
-4x-6y+5x+6y=-16+17
x=1

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.
i would say C. because since its 4 times the radius then you factor in thats only half of the circle then you factor in the other side which makes it 8 hope this is true
