You need to write 3 consecutive EVEN numbers using only one variable. multiply by 2 to ensure the numbers are even. Add or subtract 2 to get the next consecutive number.
(2x - 2) , (2x) , (2x + 2)
add them up to equal -78
-78 = (2x-2) + 2x + (2x+2)
-78 = 6x
-78/6 = x
-13 = x
the numbers are: (2(-13)-2) , 2(-13) , (2(-13)+2)
-28, -26 , -24

Answer:
Step-by-step explanation:
Begin to factor by using GCF by finding the greatest common factor. Here it is k.
We will rearrange and factor the trinomial.
Step 1: Problem
There is a class with 6 women and 12 men. a) If I randomly pick 5 students, with replacement. What is the probability that at least 4 of them will be man? b) If I randomly pick 6 students, what is the probability that at least one of them will be a man?
Step 2: Concept
1) 2a = 9b ⇒ 2:9
2) a + b = 3b ⇒ a = 2b ⇒ 1:2
Answers: 2:9 and 1:2
