Answer:

I'm assuming that the cube is labelled 1-6. There are 6 * 6 * 6 = 216 total outcomes. There are 3 evens and 3 odds so there are 3 * 3 * 3 = 27 successful outcomes. Probability will be 27 / 216 = 1 / 8.

Step 1: Define

Point (-1.25, -18.5)

Point (0.25, -30)

Step 2: Find slope m

Substitute: $m=\frac{-30+18.5}{0.25+1.25}$
Add: $m=\frac{-11.5}{1.5}$
Divide: $m=\frac{-23}{3}$

a ski chalet offers 2 weekend packages. one package provides 2 nights and 3 meals for$280. the other provides 2 nights and 5 mea

Helga [31]

1st formula 2n + 3m = 280

2nd formula 2n + 5m = 320

rearrange 1st formula to equal n:

2n = -3m + 280
 n = -3/2 m + 140

rearrange 2nd formula to equal n:

2n = -5m + 320
 n = -5/2m + 160
 so now you have

-3/2m + 140 = -5/2m + 160

Rearrange to become:
 -3/2m + 5/2m = 160 - 140
 m = 20

Now place 20 into the very 1st equation in place of the letter m
 2n + 3(20) = 280
 2n + 60 = 280
 2n = 220
 n = 110

so it costs $110 per night, $20 per meal

1 Prove that 1: sin/1-cot + cos/1-tan=cos+sin

Anit [1.1K]

Answer:

have:

$\frac{sin}{1-cot}+\frac{cos}{1-tan}\\\\=\frac{sin}{1-\frac{cos}{sin} }+\frac{cos}{1-\frac{sin}{cos} }\\\\=\frac{sin^{2} }{sin-cos}+\frac{cos^{2} }{cos-sin} \\\\=\frac{sin^{2} }{sin-cos}-\frac{cos^{2} }{cos-sin}\\\\=\frac{sin^{2}-cos^{2} }{sin - cos}\\\\=\frac{(sin-cos)(sin+cos)}{sin-cos}\\\\=sin+cos$

Solve for c: c / 3 equals 30 / 5 show your work and apply the correct order of operation

Goshia [24]

Answer:

Unless there is more to the question than c = 2 because 30 /5 = 6 and if c is 3 than 3 = 6 so simplify if needed.
