<u>Question</u><u> </u><u>:</u>
- Solve 3 [-x + (2x + 1) ] = x - 1
<u>Solution</u><u> </u><u>:</u>
⇒ 3 [-x + 2x + 1] = x - 1
⇒ 3 [x + 1] = x - 1
⇒ 3 × [x + 1] = x - 1
⇒ 3x + 3 = x - 1
⇒ 3x - x + 3 = -1
⇒ 2x + 3 = -1
⇒ 2x = -1 - 3
⇒ 2x = -4
⇒ x = -4 / 2
⇒ x = -2
D because 3% of 6000 is 210 and after one year of interest that would add up too 6210.
The answer would be either 694.7 or 694 7/10. Hope that helped!
The answer is 15 questions will be worth 4 points
if you have a total of 35 questions on a test and 20 of them are worth 2 points then you would do simple subtraction.
35-20=15
