Answer:
x=-5
Step-by-step explanation:
please tell me if im wrong lol
Answer:
x = 5
Step-by-step explanation:
6x - 3 = 3x + 12
-3x -3x
_____________
3x - 3 = 12
+3 +3
_____________
3x = 15
15 divided by 3 = 5
x = 5
You can double check this by replacing x with (5)
If it is right both sides should equal the same
6(5) - 3 = 3(5) + 12
30 - 3 = 15 + 12
27 = 27
This would prove that x = 5
Given tangent, ZN, to the circle and the arc 
= 280°, we have that
the angle formed by the chord BZ and the tangent ZN, ∠BZN is 50°
<h3>Which method can be used to find ∠BZN?</h3>
The given parameters are;
A tangent to the circle O = ZN
Required:
Angle ∠BZN
Solution;
Please find attached the drawing of the circle and tangent
From the drawing, we have;
∠BOZ = 360° - 280° = 80°
ΔBOZ is an isosceles triangle, which gives;
∠BZO = ∠ZBO
∠OZN = 90° (by definition of a tangent)
∠OZN = ∠BZO + ∠BZN
∠BZN = ∠OZN - ∠BZO
Which gives;
∠BZN = 90° - 40° = 50°
- The measure of angle ∠BZN =<u> 50°</u>

Answer:
45 markers were in each box.
Step-by-step explanation:
To solve the problem, the total number of markers must be calculated and then divided by the number of original large boxes.
The number of markers is calculated as follows:
90 left over, 15 for each teacher and there are three teachers, that is, 15 * 3 = 45
That is: 90 + 45 = 135 markers in total.
Therefore per box would be 135/3 = 45 markers were in each box.
