No, Shani is not right.
The 1st customer to get popcorn and apple juice is the 18th customer.
She missed that 18 is a common multiple of 6 & 9
Answer: y = 11
Step-by-step explanation:
first, i collected the like terms.
7y + 9 = 4y + 42
then, i moved the terms.
7y - 4y + 42 - 9
then, i collected the like terms and calculated it.
3y - 33
finally, i divided both sides.
y = 11
In the given triangle we have the following:
A. The sum of the inner angles of a triangle is always equal to 180, that is:
From this, we can solve for the sum of angles 1 and 2 and we get:
Now, we also know that angles 3 and 4 are supplementary angles and therefore their sum is 180 degrees, that is:
Solving for angle 4:
Equating both results we get:
Therefore, it is true that angle 4 is the sum of angles 1 and 2.
B. We have that the sum of angles 2 and 3 is:
If this were equal to angle 4 we would have:
B
Forgive me if I am wrong but it should be 15 hours. If she only studies 1/3 an hour a night it would take 3 1/3 nights so you'd just multiply 3 by 5. If that makes any sense. Sorry not to good at explaining things ;(
