Answer:55.73333333333
Step-by-step explanation:
We have 20% and 60% solutions and need 80 ml of 50%
A) x + y = 80
B) .20x + .60y = (80 * .5)
Multiplying A) by -.2
A) -.2x -.2y = -16 Then adding this to B) we get
.4y = 24
y = 60 ml of 60%
x = 20 ml fo 20%

Answer:
solution set={35/3}
<u>Step-by-step explanation:</u>
--3(x+5)=50
- opening brackets to simplify
3x+15=50
- subtracting 15 on both sides to find the value of x
3x+15-15=50-15
3x=35
- dividing 3 on both sides to find the value of x
3x/3=35/3
x=35/3=11.66
solution set={35/3}
hope it will help ^_^
