3x+6=3(x+2)
x-2= -(2-x)

They all had in common a 2

Answer:
7x = 35cm ; 2x = 10cm
Step-by-step explanation:
7x and 2x are the lengths
7x+2x=45
Then you take 7 + 2 = 9
so is gonna be 9x = 45
then you divide both side with 9
so is gonna be x = 5
Then you take 5 multiply 7 : 2
so 7 x 5 = 35cm
2 x 5 = 10cm

Hello,
The key to doing these problems is writing the fraction for each event and multiplying them.
I will do the first problem for you.
First, you have to draw an ace. The chances of that are 4/52.
Then, you have to draw a jack. The chances of that are 4/51.
We changed 52 to 51, because we didn't replace the ace that we drew the first time.
Multiplying those fractions gives us the answer 4/663.
I hope this gets you started in the right directions,
MrEQ
