Answer:
b = 74
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles in a triangle
b-44 + b+18 = b+48
2b-26 = b+48
Subtract b from each side
2b-b-26 =b+48-b
b-26 = 48
Add 26 to each side
b-26+26 = 48+26
b =74
To divide fractions, you flip the denominator and then multiply it by the numerator.
-6 / 5 x (-25 / 3)
Multiply straight across; the negative cancels out.
150 / 15
This can be reduced to 15, which is its simplest form.
I think this system is consistent and dependent
Answer:
55 adult tickets were sold on Friday.
Step-by-step explanation:
A linear system will be used to model the system.
Let c be the number of child tickets and a be the number of adult tickets
Then according to given statements
From equation 1
Putting this in equation 2
Putting c = 78 in equation 1
Hence,
55 adult tickets were sold on Friday.
