Answer:
x=-28
Step-by-step explanation:
-3(x-1)+8(x-3)=6x+7
1) Distribute -3 to x and -1:
-3x+3
2) Distribute 8 to x and -3:
-3x+3+8x-24=6x+7
3) Combine alike terms:
5x-21=6x+7
4) Subtract 5x from both sides:
-21=x+7
5) Subtract 7 from both sides:
Footnotes:
The <u>Distributive</u> property says a(b+c)=ab+ac
no it = -3x +3 + 8x - 24 = 5x + 21
i think u dont need explaination so...
Answer: 53.95
57.6
12 x 0.80 = 9.60
9.60 x 6 = 57.6
(-2,-6) (6,2)
It is binomial:
p= 0.75 = 75%
1-p = 0.25 = 25%
N = 10
k=7
"seven successes in 10 trials"
(10 choose 7) (0.75)^7 ( 0.25)^3 =
(10*9*8 / 3*2) * (0.75)^7 ( 0.25)^3 =
(5*3*8) (0.75)^7 ( 0.25)^3
120 (0.75)^7 ( 0.25)^3
= 0.25028228759765625
or just over 25%
