Convert the mixed number 2 1/4 into an improper fraction: 9/4.
Then multiply this 9/4 by 3: 27/4, or 6 3/4.
Answer:
20
Step-by-step explanation:
If the two triangles are similar, then corresponding sides must share a constant ratio. This means that:
![\dfrac{10}{6}=\dfrac{25}{15}=\dfrac{x}{12}](https://tex.z-dn.net/?f=%5Cdfrac%7B10%7D%7B6%7D%3D%5Cdfrac%7B25%7D%7B15%7D%3D%5Cdfrac%7Bx%7D%7B12%7D)
Let's use the second ratio:
![\dfrac{25}{15}=\dfrac{x}{12}](https://tex.z-dn.net/?f=%5Cdfrac%7B25%7D%7B15%7D%3D%5Cdfrac%7Bx%7D%7B12%7D)
Multiply both sides by 12:
![\dfrac{25\cdot 12}{15}=x \\\\x=20](https://tex.z-dn.net/?f=%5Cdfrac%7B25%5Ccdot%2012%7D%7B15%7D%3Dx%20%5C%5C%5C%5Cx%3D20)
Hope this helps!
Since there are 3 note books for 16 dollars and he bought 2 note books 3times 2 then the 6 dollars from the 3 times 2 u do 6 plus 5 and ur remainder is ur whole number
None of the answers in my opinion is correct This is because if we try solving this expression we obviously first have to apply bodmas rule which states that brackets should be solved firstly and then division, multiplication, addition and then subtraction.
So if we apply bodmas here we will first do 82 / 22 which come out to be 3.72 and then we will add 22 to 3.72 which becomes more than 20 obviously which is the largest options in the answer. Hence all options are incorrect.
