Answer:

y greater than or equal to 14
Step-by-step explanation:
Given the inequality:

We solve it by isolating the variable y on one side. That is, in our case we add 27 to both sides and get:

25 is the length of x, using the 30-60-90 special triangle method
Step-by-step explanation:
Let's solve for c.
5c=d
Step 1: Divide both sides by 5.
5c
5
=
d
5
c=
1
5
d
If the two angles of the triangle are equal. Well yes, because if the angles are both 50 degrees then the other angle will be 30. but it also depends on the shape of the triangle if they differ.
The answer is 640 because if you multiply the total student of 6h grade by 100 and divide by 30. You will get the total of student in the school
