<h3>Answer:</h3>
D. If x2 = 9, then x = 3.
<h3>Explanation:</h3>
The converse reverses the order of phrases in "if p then q" so it becomes "if q then p". Here, that makes the converse ...
... If x^2 = 9, then x = 3.
The converse is not true (x may be -3), so we're finished with the problem. The appropriate choice is the one indicated above.
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
Depends on the formula, but with most cases yes, because you may have -3 as an answer, but adding only 4 makes it positive.
There are some cases where you could look at it and know the sign, like if I am adding -100 and -93, I know the answer will be negative
