So you would start with 40/n because quotient means division and then it would be (40/n) - 13 (40 divided by n then minus 13) because the answer is thirteen less than the quotient of those numbers. since it wants you to evaluate for n=2 you would do 40/2 which is 20 then subtract 13 which is 7.
So write the expression as (40/n) -13 and when you evaluate just stick the 2 where the n is for (40/2) - 13
20 - 13
= 7
Answer:
D
Step-by-step explanation:
Answer:
Angle ABF is 120°.
Step-by-step explanation:
Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.
Answer:
5
Step-by-step explanation:
If two is subtracted from a number: let's give the number a name and call it X . And this difference is tripled: so we get 3(X−2) . The result is 4 more than the number, so
3(X−2)=4+X .
We want to know X so we need to get it to one side of the equation. That's done by repeatedly doing the same operation on both sides of the equation. First get rid of the parentheses:
3X−6=4+X.
Now subtract X and add 6 :
2X=10
Divide by 2:
X=5
