Answer:
52 because in 1 cup equivalent to 8 ounces.. if she drinks 6 cups that is 48 ounces plus the half cups 4 ounces so 52 ounces all in all
Answer:
Step-by-step explanation:
The equations would look like this:
x + 8x + x + 100 = 840
Combine like terms.
10x + 100 = 840
Subtract 100 from each side.
10x = 740
Divide both sides by 10.
x = 74
So, that makes one of the numbers 74.
Now, we're gonna substitute 74 into 8(x) to find the second number.
8(74) = 592
So, the next number is 592.
592 + 74 = 666
840 - 666 = 174
So, the numbers are 74, 592, and 174
If you'd like to check the answer, plug the numbers back into the equation:
74 + 8(74) + 74 + 100 =
840.
