Answer:
The results don't make sense
Step-by-step explanation:
We can solve by means of a 2x2 system of equations, we have to:
"x" is the number of children's tickets
"y" is the number of adult tickets
Thus:
8 * x + 8.75 * y = 259
x + y = 35 => x = 35 - y
replacing we have:
8 * (35 - y) + 8.75 * y = 259
280 - 8 * y + 8.75 * y = 259
- 8 * y + 8.75 * y = 259 - 280
0.75 * y = -21
y = -21 / 0.75
y = -28
Thus:
x = 35 - (-28) = 63
With these results we notice that the problem has inconsistency, since the value of the tickets cannot be given a negative number, I recommend reviewing the problem, since the approach is correct.
The answer would be x=7.
I hope this helps!
Apologies for this being answered late.
Answer:
Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure <em>Part</em><em> </em><em>A</em><em> </em>out:
180° = 22° + x° + 104°
180° = 126° + x°
-126° - 126°
___________
54° = x
_______________________________________________
The measure of ∠C and the exterior angle measure of 105° sums up 180°, according to the Linear Pair Theorem:
180° = 105° +
-105° - 105°
______________
Then use the Triangular Interior Angles Theorem to figure out the :
180° = 53° + 75° +
180° = 128° +
-128° - 128°
______________
OR, you can use the Exterior Angles Theorem, which states that the exterior angle is opposite the side with two interior angles, so you would deduct the first interior angle from the exterior angle to get the measure of the second interior angle. In this case, you would deduct 53° from 105° to get 52°:
142° = 53° + m∠A
- 90° - 90°
_______________
_______________________________________________
The measure of ∠N and the exterior angle measure of 142° sums up 180°, according to the Linear Pair Theorem:
180° = 142° +
- 142° - 142°
______________
Then use the Triangular Interior Angles Theorem to figure out the :
180° = 38° + 90° +
180° = 128° +
- 128° - 128°
______________
OR, you can use the Exterior Angles Theorem, which states that the exterior angle is opposite the side with two interior angles, so you would deduct the first interior angle from the exterior angle to get the measure of the second interior angle. In this case, you would deduct 90° from 142° to get 52°:
142° = 90° + m∠M
- 90° - 90°
