Given information:
A fence on a hill uses vertical posts L and M to hold parallel rails N and P
The diagram is attached below
Here lines N and P are parallel lines
Transversal line for parallel lines N and P is line L
Calculation:
angle 1 and angle 16 are consecutive exterior angles
If parallel lines are cut by a transversal then consecutive exterior angles are supplementary.
<em><1 +< 16 = 180</em>
<em>115+ < 16 = 180</em>
<em>< 16 = 180 - 15</em>
<em>< 16 = 65</em>
<em />
<em>So measurement of angle 16 = 65 degrees.</em>
<em></em>
I think we’re talking about the 15, the smallest number for 15 would be 3. Because 3 x 5 = 15
Answer:
B) x+y=120; 12x+20y=1720
Step-by-step explanation:
If variables are defined as ...
x = number of student tickets sold
y = number of adult tickets sold
then the problem statement can be modeled by ...
x + y = 120 . . . . . . the total number of tickets sold is 120
12x + 20y = 1720 . . . . . the total collected from ticket sales was $1720
___
Total revenue is the sum of the revenues from sales of each ticket type. The revenue from a given ticket type is the product of that ticket price and the number sold.
Answer:
- 8
Step-by-step explanation:
Given
x² - 64 = 0 ( add 64 to both sides )
x² = 64 ( take the square root of both sides )
x = ± = ± 8
Solutions are x = 8 and x = - 8
