-7x2p= -14p
-7x-4k= 28k (negative x negative = positive
-14p+28k=....
2xp=2p
2x1=2
-14p+28k+2p+2
(-14p+2p) +28k+2
-12p+28k+2
or
28k-12p+2
The jet could fly 2,000 miles in 8 hours and the rate of speed is 250miles per hour.
7 units bc I took the test already
Answer:
9 hours
Step-by-step explanation:
$56.00 -------> 7 hours
$1 ---------------> (7 / 56) hours
$72 -------------> (7/56) x 72 = 9 hours
The bisector of the angle at A (call it AQ) divides the segment BC into segments BQ:QC having the ratio AB:AC. Use this fact to find x.
.. 9:15 = (2x -1):3x
.. 15(2x -1) = 9*3x . . . . . the product of the means equals the product of extremes
.. 30x -15 = 27x
.. 3x = 15
.. x = 5
___
According to the value of x, the bisector AQ divides the triangle into two isosceles triangles: ABQ, ACQ.
