Answer:
Step-by-step explanation:
(1) P = 5G
(2) G + P = 30
Substituting (1) into (2) gives:
G + 5G = 30
6G = 30
G =5
So there are 5 green pencils.
Now using that in (1) gives us P = 5 x 5 = 25
So there are 5 green pencils and 25 purple pencils.
Rewrite <span>2cos x + 1 = 0 as:
2 cos x = -1, and then cos x = -1/2
x must be in Quadrant II or Quadrant III, since the adj. side is negative.
Note that the angle 120 has adj. side -1 and hyp 2. So 120 degrees is one solution.
Now what about a possible 2nd solution, to be found in Quadrant III? That would be -120 degrees, which has the same terminal line as does 240 degrees.
No soap.
So, the solution is 120 degrees.</span>
This answer us 16.97
you do square root of 288 and it will give you the answer of 16.97
So 0.25 is essentially 25/100. Divide 25 from the top and bottom to get 1/4
4y/3 - 3/4 + 5/6y (multiply by) x 2 + 4
4y/3 - 3/4 + 5y/3 + 4
collect like terms: (4y/3 + 5y/3) + ( - 3/4 + 4)
simplify: 3y + 13/4 <----- FINAL ANSWER
