The point on the line, -1/3, shows the opposite of 1/3, or the opposite of the opposite of -1/3
Answer: B. 30
Step-by-step explanation:
First, you re-write the expression
6(-3.5) + 15(4) - 12(3/4)
Then multiply all the parts correctly.
-21 + 60 - 9
-21 + 60 = 39
-9
= 30
There are 74.227 milliliters of acid in the solution.
Explanation:
- The total amount of liquid is 373 milliliters. This is both the acid and water combined i.e amount of liquid + amount of acid = 373 milliliters
- If 19.9% of this is acid it means 19.9% of the the entire 373 milliliters is acid. So we calculate how much 19.9% of 373 milliliters is.
- 19.9% of 373 milliliters = 0.199 × 373 = 74.227 milliliters. So 74.227 milliliters of the entire solution is acid.
Answer:
A) SUBTRACT 3x by both sides of the bottom equation.
