Helen subtracted 17 from the right side of the equation when she should have added 17. Adding 17 to both sides would have gotten x/y by itself.
The answer is 'Helen should have added 17 to both sides of the equation'.
To find mean all you have to do is add all the numbers up and divide ny how many numbers there are. If you add them all together is equals 1295. now divide that number by the amount of numbers there are which is 10, and divide 1295 by 10. You get 129.5
You could easily do that yourself, with a pencil, and about the same amount of time it took you to post the question here.
If you go through and try them . . . 1/1, 1/2, 1/3, 1/4, 1/5 . . . etc., you'll find
that the thirds, sixths, sevenths, and ninths produce repeating decimals.
The oneths, tooths, fourths, fifths, eighths, and tenths don't.
Answer:
<h3>B. -84</h3>
Step-by-step explanation:
Taking the determinant of the matrices we will have;
= 4x(5y) - 2x(3y)
= 20xy - 6xy
= 14xy
Given x = -2 and y = 3
Determinant = 14(-2)(3)
Determinant = -28*3
Determinant = -84
