Answer:
1 is 27.8%
2 is 41.7%
Step-by-step explanation:
To calculate 1 there is a 10/36 chance (2, 3, 4, 5 out of possible roles of 2 - 12)
To calculate 2 there is a 15/36 chance (2, 3, 5, 7, 11 are prime)
Answer:
B and D
Step-by-step explanation:
Answer: Karen has 20, Trey has 15, Dante has 40
Step-by-step explanation:
Karen=x+5 Trey=x Dante=2x+10
x+x+5+2x+10=75
4x+15=75
4x=60
x=15
6x - 3y = 15.....multiply by 4
7x + 4y = 10....multiply by 3
---------------
24x - 12y = 60 (result of multiplying by 4)
21x + 12y = 30 (result of multiplying by 3)
---------------add
45x = 90
x = 90/45
x = 2
6x - 3y = 15
6(2) - 3y = 15
12 - 3y = 15
-3y = 15 - 12
-3y = 3
y = -3/3
y = -1
solution is (2,-1) <==
