Answer:
0
Step-by-step explanation:
11a + 9b + c + 2a
a constant is just a number...it has no variables (letters).
there are no constants in this expression
example :
3x + 2b + 7 + 4c + 2 x + 5 = 8
the constants in this are 7 and 2 constants are 5 and 8
Well, you need
1: at least one variable
2: A formula... example: f(x)
3: numbers
Let, amount of 14% solution required is x ounces.
So, amount of 8% solution will be ( 28 - x ) ounces.
Now, mathematical equation is :
Therefore, amount of 14% solution and 8% solution required is 4 ounces and 24 ounces respectively.
Hence, this is the required solution.
