Answer: x<−28
Step-by-step explanation:
To solve equations like this we need to do inverse operations.
First we need to build an equation: 9+3x=21
We pass the nine to the other side, subtracting the 9 to 21, that leaves us with 3x=12
After that we just divide 12 by 3, wich gives us x=4, or, as it says in the question: n=4
Now let's double check:
N=4, since 3*4=12 and 12+9=21
Hope it is helpful :)
Answer:
9/169
Step-by-step explanation:
JQK of 4 suits = 12 cards
12/52x12/52=
3/13x3/13=
9/169
I always had trouble with these too.
The correct answer is: SSS
I think it could possibly be the 3rd one but I’m not too good with math
