Alex's score for a game is given by the expression 9-8.2-(-1.9). Beth's score for the game is -8-(-5.4)-1.8. Whose score was higher?
9 - 8.2 + 1.9
versus
-8 + 5.4 - 1.8
well right off the first one ends up positive and the second ends up negative :)
To compare Alex's and Beth's scores, we need to evaluate the given expressions for their scores.
Let's first evaluate Alex's score expression:
9 - 8.2 - (-1.9)
To simplify this expression, we'll start by removing the double negatives:
9 - 8.2 + 1.9
Next, we subtract 8.2 from 9:
0.8 + 1.9
Adding these two numbers together, we get:
2.7
So, Alex's score is 2.7.
Now, let's evaluate Beth's score expression:
-8 - (-5.4) - 1.8
Again, we'll remove the double negatives:
-8 + 5.4 - 1.8
Subtracting 5.4 from -8, we get:
-2.6 - 1.8
Subtracting 1.8 from -2.6, we get:
-4.4
Therefore, Beth's score is -4.4.
Comparing the scores, Alex's score (2.7) is higher than Beth's score (-4.4).
