4/5 of his total trip is 480...
4/5x = 480
x = 480 / (4/5)
x = 480 * 5/4
x = 2400/4
x = 600 <=== total distance is 600 miles
Pi is actually one of the letters of the Greek alphabet, but it is most known in the math field as the ratio between the circumference of a circle and the circle's diameter.
There is no exact measure of pi, as it does not terminate but it starts like:
3.14159265
Answer:
x=4
Step-by-step explanation:
You put 9x+6y=78 over 3x-6y=-30. Then, you are going to add the two equations. So, you are going to do 9x+3x, 6y-6y (since the second 6 is negative, it ends up subtracting), and 78-30. You will end up canceling the 6y's, and end up with 12x=48. Then, you will divide 48 by 12, and get x=4. Hope this helped:)
Answer:
-12i^2 + i +6
Step-by-step explanation:
(2 + 3i)(3-4i)
6 - 8i + 9 i - 12i^2
combine like terms
-12i^2 + i + 6
Hope this Helps!!!
