Answer:
200 mL
Step-by-step explanation:
If x is the volume of solution B:
0.06 (500) + 0.20 x = 0.10 (500 + x)
30 + 0.20 x = 50 + 0.10 x
0.10 x = 20
x = 200
Answer:
0.04
Step-by-step explanation:
........ i just divided it
Equation
-4x + 16 = -116
solve for x
-4x + 16 = -116
subtract 16 to both sides
-4x + 16 - 16 = -116 - 16
simplify
-4x = -132
divide -4 to both sides
-4x/-4 = -132/-4
simplify
x = 33
answer: the number is 33
