Disclamer: the following is confusing but I will transcribe what is going on in my head
3:4, 3+4=7
4:5, 4+5=9
hm
we can do fractions
3:4, 4 units is yellow
4/7 of all is yellow
4:5, 5/9 of all is yellow
all end is all-9
yellow intial=6+yellowfinal
yellowinitial=(4/7)all
(let's say all=x)
yi=(4/7)x
final=(5/9)(x-9)
yi=6+yf
(4/7)x=6+(5/9)(x-9)
times both sides by 63
36x=378+35(x-9)
distribute
36x=378+35x-315
36x=35x+63
minus 35x both sides
x=63
yellow=(4/7)(x)
yellow=(4/7)(63)
yellow=36
there wer 36 originally
Answer:
-14.120 Radians
Step-by-step explanation:
To convert, use this angle degrees to radians formula:
Radians = Degrees x ( Pi / 180)
Try using this formula
5.50 x 3.87 equals 21.285. 21.285 rounded to the nearest cent is $21 dollars and 3 cents.
7y^2 - y^2 = 6y^2
hope it helps
- Move 4y to the front so it should be 4y=12-3x
- Divide the equation like how I did in the picture above then you should have y=3-3/4x
- Then you switch it to y=-3/4x+3 and that's your answer.
Now for 6x+2y=6
- Move 2y to the front so it looks like 2y=6-6x
- Then you divide the equation by 2 like in the photo above and that should give you y=3-3x
- Finally you switch the equation to y=-3x+3 because we are using the Slope Intercept Form. (Y=mx+b). That's your answer.
Sorry if my handwriting is bad.
