Answer:
x = 71
Step-by-step explanation:
18(x + 1) = -54
to start off, subtract 18 from both sides
18 - 18(x + 1) = -54 - 18
that should give you
x + 1 = 72
(its safe to take out paranthesis from problem by now) now take away 1 from each side
x + (1 - 1) = 72 - 1
that should give you
x = 71
It would be a 4 in 28 probability (or 1 in 7 if you simplify)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
first you add up all the number of combs together which gives you 28 combs total
the there were 4 blue combs out of the 28
so the probability it 4 in 28 or 1 in 7
Bryant's score is 55 (given)
Jack's score is twice the score of Bryant, so it's
![55\cdot 2 = 110](https://tex.z-dn.net/?f=55%5Ccdot%202%20%3D%20110)
Brenda's score is 13 less than Jack, so it's
![110-13 = 97](https://tex.z-dn.net/?f=110-13%20%3D%2097)
