Answer:
Answer 1)
Step-by-step explanation:
Starting with 1 + 3x = -x + 4, add x to both sides. Result: 1 + 4x = 4
Next, subtract 1 from both sides, obtaining 4x = 3.
Finally, divide both sides by 4: x = 3/4
This matches Answer 1).
Hope you can read my horrible handwriting!!!!
Im pretty certain that the equation should be:
15x + 9x
Answer:
Step-by-step explanation:
Equation:
acid + acid = acid
0.05x + 1.0(95-x) = 0.30*95
----
Multiply thr by 100 to get:
5x + 100*95 - 100x = 30*95
---
-95x = -70*95
---
x = 70L (amt of 5% solution needed)
---
95-x = 25L (amt of 100% solution needed)
==================================================
How many Liters of 100% acid should be used to obtain the solution?
