Answer:
-54
Step-by-step explanation:
8a + 7b + c = 9
We want -6c, but we have c in the equation so multiply by -6
-6(8a + 7b + c) = 9*-6
-48a -42b -6c = -54
Rearranging the equation
-6c - 48a - 42b = -54

Answer:
10.1%
Step-by-step explanation:
The first thing we should do is calculate the total volume of the solution when mixing them would be:
0.7 + 0.3 = 1
Now, we have that the resulting concentration (x) would be equal to the sum of the multiplications between the volumes and the concentrations to be mixed, as follows:
x * 1 = 0.7 * 0.05 + 0.3 * 0.22
x = 0.035 + 0.066
x = 0.101
That is, the concentration of the resulting mixture would be 10.1% (0.101 * 100)
