Answer:
x = -4
Step-by-step explanation:
-5x-4x-2 = -8x+2 is the only one with a solution.
-5x-4x-2 = -8x+2
-x-2 = 2
-x = 4
x = -4
Let a = speed of the plane A, and b = speed of plane B.
(Assume that the net effect of the wind is negligible.)
From the first sentence, the distance between A and B after each travels for 1 hour is a + b miles. From the second sentence, after 45 minutes, or 0.75 hour, the distance between A and B is 200 miles. Plane a has traveled 0.75a, while plane B has traveled 0.75b.
Hence a + b = 0.75a + 0.75b +200
==> 0.25(a + b) = 200.
==> a + b = 800.
Therefore planes A and B are 800 miles apart now.
It goes 19 1 and 4ths to the area surface
Answer:
6
Step-by-step explanation:
First, simplify the exponents:
2*(3^6*3*-5)
2*((3*3*3*3*3*3)*(1/3*3*3*3*3))
2*(729*0.00411522633)
Then solve from there:
2*2.99999999457
5.99999998914
Since there is only whole numbers and a fraction present, im assuming you have to round:
5.99999998914
6
6 is your answer
Hope this helps!
