A standard trick for finding the rational form of a repeated decimal:
Multiply by an appropriate power of 10 to move one "cycle" of the repeated pattern to the left side of the decimal point:
Now subtract
from this number and we lose the fractional part:
And from here you can solve for
.
Your answer is 8500 because 850 times 10 equals 8500
Answer: Yes
Step-by-step explanation: A triangle can be formed because A+B>C
A and B are 2.9 and 4.8
Since those numbers have the least value
I added both and found that A and B are equal to 7.7
7.7>7.4
These sides could form a triangle
Answer:
D) 2x² + x - 10
Step-by-step explanation:
First, distribute the negative sign to all terms within the second parenthesis:
- (4x - x² + 6) = -4x + x² - 6
Next, combine like terms:
5x + x² - 4 - 4x + x² - 6
(x² + x²) + (5x - 4x) + (-4 - 6)
2x² + x - 10
2x² + x - 10 , or D) is your answer.
Hello there! Your answer would be: each persons share was $4.46.
Okay, so to solve this divide the total amount by the number of people there. Note that the equation says "Nina and 3 friends" indicating that Nina is one of these people, and there are 3 others, so we have 4 in total.
$17.84 ÷ 4 = $4.46
So, each person paid $4.46. I hope this helped, and have a great rest of your day! :)
