Answer: 5.25 or 5.5 [see note]
Step-by-step explanation:
1/4 (15 – 6) +3 <em><u>[I'm not clear what is meant by the " : 12," so I left it out.]</u></em>
1/4 (9) +3
9/4 + 3
2.25 + 3 = 5.25
===
If it is supposed to read
1/4 (15 – 6) +3/12
Then it would be
5.25 + 0.25 = 5.5
For this case we must solve the following equation:
![x ^ 2 = 3](https://tex.z-dn.net/?f=x%20%5E%202%20%3D%203)
So we have to:
Applying square root to both sides of the equation:
![x = \pm \sqrt {3}](https://tex.z-dn.net/?f=x%20%3D%20%5Cpm%20%5Csqrt%20%7B3%7D)
Thus, we have two roots:
![x_ {1} = \sqrt {3} = 1.7321\\x_ {2} = - \sqrt {3} -1.7321](https://tex.z-dn.net/?f=x_%20%7B1%7D%20%3D%20%5Csqrt%20%7B3%7D%20%3D%201.7321%5C%5Cx_%20%7B2%7D%20%3D%20-%20%5Csqrt%20%7B3%7D%20-1.7321)
Answer:
![x_ {1} = 1.7321\\x_ {2} = - 1.7321](https://tex.z-dn.net/?f=x_%20%7B1%7D%20%3D%201.7321%5C%5Cx_%20%7B2%7D%20%3D%20-%201.7321)
Answer: 6 and 1/12 cups
Step-by-step explanation:
For this problem, we add 3 and 2/3 + 1 and 3/4 + 2/3. We can change these mixed numbers into improper fractions to make the math easier:
11/3 + 7/4 + 2/3
Next, we can add the 11/3 and 2/3 since they have the same denominator (bottom number). This gives us 13/3.
13/3 + 7/4
Now that we have two fractions, we just add them together. This leaves us with 6 and 1/2.
If you're having trouble with adding fractions with denominators that aren't the same, here are some videos (if you can't click the link, just copy and paste into the search bar):

y=2x+3 (the 3 can be changed)
Your question seem to me non-understandable. Are they adding up together ?
or multiplying ?
