Answer: B
Step-by-step explanation:
An ordered pair is another way of saying “point” or “coordinate”. Knowing that, we know A and C are expression and equation, respectively. We are left with B and D. We know that B is the correct answer because that is the proper way to write an ordered pair, or coordinate. Therefore, B is the answer.
Answer:
20(4 + 5)
Step-by-step explanation:
GCF is just the biggest number each value can be divided by. Here, it's 20, so that goes outside of the parenthesis. Now, what can you multiply by 20 to get 80? 4, so that goes in the second box. What can you multiply by 20 to get 100? 5, so that goes in the last box. You can check your answer by doing 80 + 100 = 180; 20(9) = 180.
Answer:
B
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = 
= 
, then
x = 
( ) ≈ 57° ( to the nearest degree ) → B
