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:
what do you mean it's not 7 it is 7
Step-by-step explanation:
The value of x is 7
The given parameters are:
\angle BAE = 9x + 2∠BAE=9x+2
\angle BAD = 130^o∠BAD=130
o
Line AE is the angle bisector of \angle BAD∠BAD
This means that:
\angle BAD = 2 \times \angle BAE∠BAD=2×∠BAE
So, we have:
130 = 2 \times (9x + 2)130=2×(9x+2)
Divide both sides by 2
65 = 9x + 265=9x+2
Subtract 2 from both sides
63 = 9x63=9x
Divide both sides by 9
7 = x7=x
Rewrite as:
x = 7x=7
Hence, the value of x is 7
