Answer:
7x-2, -x-6y+16, 5x-3
Step-by-step explanation:
I'm guessing the three expressions are:
1. 3(x+2) + 4(x-2)
2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
3. 2(4x+3) - 3(x+1)
... 1. 3(x+2) + 4(x-2)
= 3x + 6 + 4x - 8
= 7x - 2
... 2. 2(x+y) - 3(x+y) - (y+8) + 4(6-y)
= 2x + 2y - 3x - 3y - y - 8 + 24 - 4y
= -x - 6y + 16
... 3. 2(4x+3) - 3(x+1)
= 8x + 6 - 3x - 3
= 5x - 3
Answer:
0.2857
Step-by-step explanation:
We define the time it takes to do these dishes to be uniformly distributed between the time 5 minutes and 12 minutes.
a = 5 minutes
b = 12 minutes
Probability of tonight's dish washing being between 6 and 8 minutes
P(6<X<8)
= 8-6/b-a
= 2/12-5
= 2/7
= 0.2857
The probability it will be better 6 and 8 minutes is therefore 0.2857
Not sure what you're asking. are you wanting to solve 5 ( a - b), where b equals those two things listed below? If that's the case, I can definitely help. If not, please clarify.
If each game costs 2 tokens, 120 tokens would equal 60 games.
