Answer:

B

Step-by-step explanation:

Now, according to the math, it SHOULD land on 50 every time, but let's be real, it wont.

So, since its 150, divide that by the amount of locations hes chosen, and that gives you 50. Now, again, it should, but it probably wont.

Hope this helped. Please mark this brainliest if you feel this was answered how it should. Let me know if you need any other kind of help and i am more than happy to assist.

Lauren is shopping and finds 6 bracelets, 2 pairs of earrings, and 3 necklaces that she likes. How many ways can Lauren select 4
Grace [21]
Because it does not specify that she has to choose one or two from each category all pieces of jewelry can be treated as choices in a combination set.

the formula for a combination is

C(n,r)= \frac{n!}{r!(n-r)!}

where n is a total number of choices ( 11 ) 
and r is number chosen out of those choices (4)
 so

C(11,4)= \frac{11!}{4!(11-4)!} 

She has 330 possible choices  to come home with 4 pieces of jewelry

If DE=4x+10, EF =2x-1, and DF=9x-15, find DF
svetoff [14.1K]

Answer:


Step-by-step explanation:

If DE = 4x+10,EF =2X -1, and DF= 9x - 15 find DF

(de + ef ) - df = 2e || 2e/2 = e || ed - e = d || ef - e = f || f + d =  df

de + ef = 6x + 11 || (6x +11) - df = -3x -6 || 2e/2 = -3x/2 - 3  || (-3x/2 - 3) - de = x/2 + 7||  (- 3x/2 - 3) - ef = -x/2 - 1|| d + f = 6
