Answer:
what graph
Step-by-step explanation:
Answer:
10 liters.
Step-by-step explanation:
Let the volume of 2% acid be x liters.
Then the volume of the 8% solution will be (x + 30) liters.
Work in amounts of pure acid: amount of acid in the 10% solution = 30 * 0.1
= 3. So we have the equation:
0.02x + 3 = 0.08(x + 30)
0.08x - 0.02x = 3 - 0.08*30
0.06x = 0.6
x = 10
So the answer is 10 liter of the 2% solution.
Subtract 7, so the answer is x <= 3, or C.

Answer:
Answer: one fourth
Fourth is a word that used to describe a number value of 1/4. To answer this question, you need to change the number you got (3/12) into x/4 form. To convert 12 into 4, then you need to divide the numerator and denominator with 3. The equation would be (3/3)/(12/3)= 1/4.
To determine how much fourth the number has, you need to divide the result with 1/4. The calculation would be: (1/4)/ (1/4)= one fourth
hope its help
