Answer:
Option D
Step-by-step explanation:
Given: set of inequalities
To find: Points which do not satisfy all the inequalities
Solution:
For point
:

So, (15, 0) satisfies all the inequalities
For point
:

So, (7.5, 7.5) satisfies all the inequalities
For point (22.5,2.5):

So, (22.5,2.5) satisfies all the inequalities
For point (7.5 ,0):
Put s = 7.5 and t = 0 in 
which is false
So, 
Answer:
Option 5.
Step-by-step explanation:
Ok, start with parentheses and then a 6 x inside it.
Then put a mini 3 on top.
7root all of that- you get option 5.
k-4/3= 3
Mutiply both sides by 3 .
(3)(k-4/3)= (3)(3)
Cross out 3 and 3 , divide by 3 and then becomes k-4= 9
Move -4 to the other side
Sign changes from -4 to +4
k-4+4= 9+4
k= 13
Answer: k= 13
If he ate 6/8 of the pizza, that means 2/8 is left.
2/8 simplify it, by dividing it by 2 and your answer is...
IT'S 1/4
