so.. whatever "x" is, we know 1125 + x = y
and whatever the alcohol concentration yield may be, we know
(1125)(0.9) = 0.75y
(1125)(0.9) = 0.75y <--- solve for "y", that's how much the final amount of milliliters will be
how much pure water was added? subtract 1125 from that, or y - 1125
The value of x is 3
Step-by-step explanation:
<u>Equation:</u>
3(x+1)-8=14-2(3x-4)
<u>1. Open the brackets</u>
3(x+1)-8=14-2(3x-4)
3x + 3 - 8 = 14 - 6x + 8
<u>2. Bring all x variables on the left side</u>
3x + 6x = 14 + 8 + 8 - 3
<u>3. Solve</u>
9x = 27
x =
x = 3
Therefore, the answer of x is 3.

Answer:
Step-by-step explanation:
Let Kat reads k pages of the book.
Miguel reads 5 times as many pages of the book as Kat. So,
m = 5k ...(1)
Together they read 54 pages. i.e.
m+k = 54 ...(2)
From equation (1),
Hence, the equation that can be used to find how many pages Kat read is equal to .
