Answer:
Easiest to pick (0, 0) and (1, 1) probably, then slope is 1.
Step-by-step explanation:
Rise over run for (0, 0) and (1, 1) is rise up 1 and run over 1, so 1/1.
This means slope is 1
Divide 10 by 25, which would get you 4. Move the decimal over two to the left, because you wanted a percentage.
Jenny gave away 40% of the roses.
Let x represent the number originally signed up.
.. 360/x -6 = 360/(x +3)
.. 360*(x +3) -6x(x +3) = 360x . . . . . multiply by the product of denominators
.. 360x +1080 -6x^2 -18x = 360x
.. x^2 +3x -180 = 0
.. (x +15)(x -12) = 0
Solutions are x = {-15, 12}
12 members went on the trip.
_____
The problem wording does not make clear whether the original number (12) or the number suggested by the bus company (15) went on the trip. It would be most reasonable for 15 to go, if the troop had people who were willing.
Answer: Both numbers 6/5 and 3/2 do not have a common denominator. Just as how 2 cannot go into 5 evenly.
It's answer will be 36x10^5
As we have
(4x10^10)(9x10^-5)
All terms of this expression are being multiplied
So we will solve it in two parts, simple terms and terms having powers
(4x9)(10^10x10^-5)
As we know when same terms having some powers are multiplied, their powers are added
(36)(10^(10-5))
(36)(10^5)
So it will become
36x10^5
