Answer:
There were 40 student tickets sold.
Step-by-step explanation:
First I set up equations to represent this situation.
4x+3y=380
x+y=105
x represents the adult tickets and y represents the student tickets.
I can solve this with the elimination method. I want to cancel out the x so I will multiply every term in equation 2 by -4.
4x+3y=380
-4x-4y=-420
Now I combine like terms.
-y=-40
I can divide the negative one from both sides.
y=40
The answer to your question is -34
<u>Answer:</u>
Option (C)
The new wall will be 42 foot long
<u>Explanation:</u>
Given a 14-foot wall in reality equals 2 inches in drawing
And a new wall has to be built that measures 6 inches in the drawing
According to the question
2 inches (in drawing) = 14-foot (in reality)
6-inces (in drawing) =
= 42 foot
Therefore, the wall that measures 6 inches in the drawing will be 42 foot long in reality
Answer:
Option B
Step-by-step explanation:
By applying the converse theorem of corresponding angles,
"If corresponding angles formed between two parallel lines and the transversal line are equal then both the lines will be parallel"
Angle between line B and Y = 90°
Angle between line B and Z = 90°
Therefore, corresponding angles are equal.
By applying converse theorem, line Y and line Z will be parallel.
Option B will be the answer.
