Answer:
40 mL of 10% acid
80 mL of 25% acid
Step-by-step explanation:
x = volume of 10% acid solution
y = volume of 25% acid solution
Total volume is:
x + y = 120
Total amount of acid is:
0.10 x + 0.25 y = 0.20 (120)
Solve by substitution.
0.10 x + 0.25 (120 − x) = 0.20 (120)
0.10 x + 30 − 0.25 x = 24
0.15 x = 6
x = 40
y = 80
Answer:
B.
Step-by-step explanation:
its the same as saying..
4x - 3y = 9
x + 3y = 6
add both equation together
5x = 15
i.e X = 3
substitute x= 3 in equation 2
3 + 3y = 6
3y = 3
divide both sides by 3
y = 1
<em>-6</em> is the correct answer. Subtract and add the terms to isolate <em>x</em>.
