Answer:
If you need the answer as f by simplifying both sides of the equation and then isolating the variable, the answer would be:
Or, if you need to evaluate the function itself, the answer would be:
3 gallons of acid = 100% concentration acid
? (water+acid) gallons = 15 concentration acid
Note: Every gallon of water added reduces the percentage concentration of acid. Therefore, the relationship is inverse proportionality.
Solution:
Total number of gallons (water+acid) = (3*100)/15 = 20 gallons
Therefore, gallons of water = 20-3 = 17 gallons

I rlly don't know how u were taught to solve it but what I did was multiply all the sides
Answer:
5
Step-by-step explanation:
The easiest way to do this is to add the new members to the old and then divide by 11. Ignore the remainder.
13 + 52 = 65
65 / 11 = 5 with 10 left over. Ignore the 10. That's not a complete team.
The answer is 5
If you go on google and look up hypotnuse calculator you can find the other length, and for the angles. just thing that the interior angles of a triangle add up to 180°
