Answer:
3x+9 < - 42
Step-by-step explanation:
-4x+7x-14
3x-14>-18
3x>-4
X>-4/3
It would just be 2 teaspoons
We have 10 ml of 20% acid to which we need to add "x" milliliters of 100% acid to make 50% acid.
.20 * 10 + 1.00x = .50 * (10 +x)
in which "x" is the volume of the 100% acid to be added.
2 + x = 5 + .5 x
.5x = 3
x = 6 milliliters
