Answer:
Sound waves travel faster through liquids than through gases.
Explanation:
The output of the given algebra b = -1 - 7a with the given input of a = 6 is calculated to be; b = -43
<h3>How to solve basic algebra?</h3>
We are given the algebra;
b = -1 - 7a
where;
a is the input
b is the output
Now, we are given the value of the input to be a = 6
Thus, output is calculated as;
b = -1 - 7(6)
b = -1 - 42
b = -43
Thus, the output of the given algebra with the given input is -43.
