Answer: (2,10)
Step by Step:
y=3x+4
10=3(2)+4
10=6+4
10=10
You can solve this problem in multiple ways, but you'll have to divide the total volume with the amount per servings to find the number of servings (makes sense logically if you think about it).
The first way is to just use the fractions given. This will usually be your method in handling this if you're not familiar with it.
Convert 6 3/4 into an improper fraction. To do this, we need to put the 6 into the numerator somehow. We can approach this by multiplying the whole number (6) with the denominator (4) and adding it to (3). Basically, 6 x 4 + 3 = 27. This will be our new numerator. If you are not familiar with this concept, please let me know.
Our new fraction for the total amount of juice is
. Divide this with the amount per serving,
We flip the second fraction over and multiply it.
(I crossed out common numbers here, unfortunately I don't know how to do that here so let me know if my explanation was not clear enough. I skipped a few steps.)
18 servings would be your answer.
Or you can convert 6 3/4 into decimal, which would be 6.75. 3/8 in decimal is .375 and you can do long division from there. That way is a bit more tedious in my opinion, but sometimes more convenient.

The formula for the discriminant is the square root of b^2 - 4ac
8x^2+18x-5= 0
a = 8, b=18, c= -5
Square root of 324 +160
Square root of 484 = 22 The discriminant is 22
Answer: The number of students attend the school = 349
Step-by-step explanation:
Given: Number of students absent on Tuesday = 23
Total number of students = 372
Number of students attend the school that day = (total students) - (Number of students absent )
= 372-23
= 349
Hence, the number of students attend the school that day = 349
