Answer: 6
Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6
Let x be volume of 5% acid and y be volume of the 8%
x + y = 750 and
0.05x + 0.08y = 0.07*750 = 52.5
from first equation y = 750 - x so substituting in the second equation:-
0.05x + 0.08(750 - x) = 52.5
0.05 - 0.08x = 52.5 - 60
-0.03x = -7.5
x = -7.5 / -0.3 = 250 mls <------ answer
