Step-by-step explanation:
A:
- 5x-(3x+1)
- Expand, 5x-3x-1
- Combine like terms, 2x-1
B:
- 5x-(-3x-1)
- Expand, 5x+3x+1
- Combine like terms, 8x+1
C:
- -5x-(3x+1)
- Expand, -5x-3x-1
- Combine like terms, -8x-1
D:
- -5x-(-3x-1)
- Expand, -5x+3x+1
- Combine like terms, -2x+1
The experimental probability to choose card 1 (15/125) is 10 less than the theoretical probability which is 25/125.
Answer:
45 ways
Step-by-step explanation:
5*3*3 = 45
So we have 5x+15y=45
simplify and undistribute 5 from both sides
5(x+3y)=5(9)
divide both sides by 5
x+3y=9
multiply both sides by 6
6x+18y=54
if it was 6x+18y then the answer is 54
if it was 6x-18y, then I don't know the answer
180-(180-49-48)
180-(83)
97
180-((180-141)+(180-76))
180-(39+104)
180-143
137
180-((180-101)+60)
180-(79+60)
180-139
41
360-147-79
213-79
139
180-(360-109*2)
180-(360-218)
180-142
38
(180-118)/2
62/2
31
Hope this helps :)
