Answer:
5D-2
Step-by-step explanation:
5 times d = 5d. subtract 2 is after the 5d
I believe your answer is 8.
Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17
Solve for n as follows:
3n - 2n = n
n + 9 = 17
17 - 9 = 8
Hope this helps! :)
What is the intersection of the three sets: A = {0, 2, 3, 6, 8}, B = {2, 3, 6, 8, 9}, and C = {1, 2, 4, 8, 9}? A. {2, 8, 9} B. {

Answer:
{2,8}
Step-by-step explanation:
This is the same thing as asking what element (in this case what number) is in all 3 sets.
0 isn't in all 3 sets because it isn't in B.
2 is in all 3 sets
3 isn't because it isn't in C
4 isn't in A.
6 isn't in C.
8 is in all 3 sets.
9 isn't in A
So the elements that are in the 3 sets are {2,8}.
