(3,-1) just fill it in and the only one that makes sense is the first one
Answer:
24 out of 25 is equal to 96%
96% = A
Step-by-step explanation:
Multiply the equation:

The solution set is the same, because multiplying both sides of an equation by a non-zero number doesn't change the solution set. In fact, if you rewrite the equation as

Multiplying this by 3 (or whatever number, for all it matters) gives

Now, a product is zero if and only if at least one of the factor is zero. So, either
or 
Since the first is clearly impossible, the second one must be true, which is the original equation.
One and a half = 1.5
Three and a half = 3.5
1.5 + 3.5 = 5.
