x = 20 is the answer.
<u>Step-by-step explanation:</u>
When a parallel lines cut by a transversal, then the alternate exterior angles are congruent.
So the given 2 angles add up to 180 degrees.
5x+ 9 + 3x+ 11 = 180
8x + 20 = 180
8x = 180 - 20 = 160
x = 160/8 = 20
we know that
The least
common multiple (LCM) of two or more numbers is the least
number, other than zero, that is a multiple of all the numbers.
In this problem, we are looking for the least common multiple of 
and 
So
Multiply by
therefore
On the 
day after today, she will do both on the same day
the answer is
He can make 12 or 9 because 9x4=36 and 12x3=36
Answer:
12 units
Step-by-step explanation:
The radius is half of the diameter, so we need to double 6 to get 12.
Not really sure whats up with that inequality but she can't, if she has to spend 1.5 hours in a lab that leaves her with 5 hours. 5/4 is 1.25, so no, she can only spend 1.25 hours with each student.
