Answer:
<u>Correct answer:</u> 3
Step-by-step explanation:
I'm sorry you're going through all of that. I'm more than happy to help you figure out the correct solution for the given problem.
(5 × 3) ÷ [ 4 - 3 + (3 - 1)² ]
Following the PEMDAS Order of operations:
We must work with the numbers inside the parenthesis by multiplying (5 × 3) and subtracting (3 - 1):
= (15) ÷ [ 4 - 3 + (2)² ]
Next, you'll have to process the exponent by squaring 2:
= 15 ÷ (4 - 3 + 4 )
Then, work on the remaining terms inside the parenthesis, by subtrating 3 from 4, and adding 4:
= 15 ÷ (1 + 4)
= 15 ÷ (5)
Lastly, divide 15 by 5, which gives you the final answer, 3.
= 15 ÷ (5)
= 3

1/x = 1/2 That's what you got with your equation. So far so good. That does not tell you what x is though. You have go just a bit further.
1/x = 1/2 Cross multiply
x = 1 * 2
x = 2 It takes 2 hours to complete with all three machines working.
Answer is (-1,-2)
As where 2 lines bisect, that point be the answer. And in given scenario, both the lines bisected at (-1,-2)
11-5=6
18-11-7
26-18=8
........... so on and so forth.
I think you get the point.
