The answer is -3 because:
A negative times a postive stays negative and also:
the variable "x" has an invisible one in front of it, so,
-1 x 3 = -3

Hope this helps :)

parker correctly answered 70% of the questions on his math test. If he answered 35 questions correctly, how many questions were

Alexandra [31]

Let the total number of questions in the math test be defined by the variable x.

Now, we know that Parker correctly answered 35 questions. These 35 questions make 70% of the total number of questions on his math test.

The information we have above can be expressed as an equation given below:

70% of x=35

This can be rewritten as:

$\frac{70}{100}x=35$

Thus, to find the total number of questions we will have to isolate x.

$\therefore x=\frac{35\times 100}{70}=50$

Therefore, there were a total of 50 questions in the math test.
