Answer:
The correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].
Step-by-step explanation:
We know that the opposite of the opposite of a number, say 2, is the number itself.
That is:
Opposite of 2 is -2.
Then the opposite of -2 is:
- (-2) = 2
It is provided that:
- Justine answered a question incorrectly and lost 7 points.
- Then Meagan answered correctly and got the opposite score.
Assume that both Justine and Meagan started with 0 score.
Justine plays first.
If Justine answered a question incorrectly, his score would be -7.
Then Meagan plays, and answers the question correctly.
So, Meagan got the opposite score.
The opposite of -7 will be [- (-7)].
Thus, the correct way to represent that "the opposite of Justine's score was equal to Meagan's score" is [- (-7)].
Answer:
Step-by-step explanation:
step 1
Convert degrees and minutes to degrees
Remember that
so
step 2
Applying the law of sines
substitute the given values
solve for XZ
Using the given information, the length of WX is 26
<h3>Calculate length of a line</h3>
From the question, we are to find WX
From the given information, we have that
Point X is between W and Y
That is,
WX + XY = WY
Also, from the given information
WX= 8x + 2,
WY= 19x - 11,
and
XY = 4x + 8
Thus,
8x + 2 + 4x + 8 = 19x - 11
Solve the equation for x
8x + 2 + 4x + 8 = 19x - 11
Collect like terms
2 + 8 + 11 = 19x - 8x - 4x
Simplify
21 = 7x
x = 21/7
x = 3
Now, we can find WX
WX = 8x + 2
WX = 8(3) + 2
WX = 24 + 2
WX = 26
Hence, the length of WX is 26
