Group like terms and factor
group the ones with 8 together and the rest apart
(x²+xy)+(-8x-8y)
factor
x(x+y)+(-8)(x+y)
factor out (x+y)
(x+y)(x-8)
X=60
That’s the answer
What I did to get it
(3x-60)=120
+60. +60
3x =180
————. = 60
3
X=60
Answer:
The situation that represents this situation is:
Step-by-step explanation:
The amount of time t needed to assemble the set is inversely proportional to the number people n working.
This means that:
In which k is the constant of proportionality.
Twelve people can assemble the set in 5 hours.
This means that for . We use this to find k.
Write an equation to represent the situation.
believe the answer is 8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.
