This should be your answer I guess.
The value of n is 10.
Solution:
Given expression:
<u>To solve this expression:</u>
Add 2 on both sides of the expression.
Multiply by 5 on both sides of the expression, we get
4n = 40
Divide by 4 on both sides of the expression, we get
n = 10
Hence the value of n is 10.
(5)(2)(5)(1) could be an answer
To find the complement of an event you have to figure out what the probability is of not choosing a 6
since 1/13 is the probability that 6 is going to be choosen.
the other 12/13 is used for every other card accept for the 6:)
hope this is right
have a good one:)

(————————————————— + —————) - ————— = 0
(a + 3) • (a - 3) a - 3 a + 3
Equation at the end of step
4
:
(4a + 9) 1
————————————————— - ————— = 0
(a + 3) • (a - 3) a + 3
Pull out like factors :
3a + 12 = 3 • (a + 4)
Equation at the end of step
6
:
3 • (a + 4)
————————————————— = 0
(a + 3) • (a - 3)
3•(a+4)
——————————— • (a+3)•(a-3) = 0 • (a+3)•(a-3)
(a+3)•(a-3)
a+4 = 0
Subtract 4 from both sides of the equation :
a = -4
