12 divided by 3/2 is the same as 12 x 3/2
Do this to 8 to get the answer B
Answer: The answer is B.
Step-by-step explanation:
To figure out, you must first turn the mixed fraction (3 1/2) into an improper fraction (7/2). We can do so by:
3 * 2 = 6
6 + 1 = 7 or 7/2
Next, you follow the rules of KCF: Keep, Change, Flip. Keep the first fraction, Change the sign to its inverse operation, and Flip the second fraction.
Our original equation is 7/2 /(divided by) 3/2 = ?
1. Keep the first fraction
7/2 / 3/2 = 7/2 / 32
2. Change the sign to its inverse operation
7/2 / 3/2 = 7/2 * 3/2
3. Flip the second fraction
7/2 * 3/2 = 7/2 * 2/3
Now, solve.
7/2 * 2/3
7 * 2 / 2 * 3 = 14/6
To make this a proper mixed number, first simplify.
14/6 / 2 = 7/3
Now, figure out how many wholes are in 7/3.
7/3 / 3 = 2 1/3
This is because 2 times 3 is six, and 7 minus 6 equals 1, or 1/3.
Therefore, the answer is 7/3 OR 2 1/3 OR B

The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?
Answers
So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.
845 = 45n + 125.
Subtract from both sides:
845-125 = 45n + 125-125
720 = 45n
Divide by 45:
720 / 45 = 45n / 45
16 = n
This means that 16 bracelets can be made if the cost is 845.
We can also re-input the information into the equation to be extra sure!
845 = 45 (16) + 125.
845 = 720 + 125.
845 = 845
Yes!
I hope this helps! :)

what is 159,095 rounded to the nearest hundred?
Answers
Answer:
159,100 is the answer
Step-by-step explanation:
159,100 is the answer because 159,095 is closest to 159,100 than 159,000. So therefore, 159,100 is the answer.
Answer:
159,100
Step-by-step explanation:
200,000 - rounded to the nearest hundred thousands
160,00 - rounded to the nearest ten thousands
159,00 - rounded to the nearest thousands
159,100 - rounded to the nearest hundreds
159,100 - rounded to nearest tens
159,095 - rounded to nearest ones
While rounding off to the nearest hundred, if the digit in the tens place is between 0 – 4 i.e. < 5, then the tens place is replaced by ‘0’.
If the digit in the units place is equal to or >5, then the tens place is replaced by ‘0’ and the hundreds place is increased by 1.

The open side of the inequality sign indicates the larger number. So 5 > 3, 4 < 6.
This, ≥, means it is bigger than or equal.
To show < or >, the purple arrow points to where the unknown value (x or n or k or b etc.) could be, and the dot is unfilled, or white, indicating that number is not a possible value of the unknown number.
To show ≤ or ≥, the purple arrow works the same way, it points to the where the unknown value could be. But the dot is filled, showing that the number could be the unknown value.
So for question 11, the answer is x ≤ 0 (x is less than or equal to zero).
For question 12, the answer is x > 3 (x is more than three)

Which graph shows the correct solution to the inequality below?
Answers
Answer:
Third Option
Step-by-step explanation:
3x + 18 > 6x - 9
We have to find the value of x for this
Subtract 18 from both sides to leave 3x alone
3x > 6x - 27
Subtract 6x from both sides to be able to find the value of x
-3x > -27
Divide by -3 on both sides
x > 9
The answer would be the third option, since X is anything greater than 9
