Answer: 90 Earth years.
Step-by-step explanation:
Analizing the information provided in the exercise, you need to find the Least Common Multiple (LCM) of the given numbers.
You can follow these steps:
1. You must descompose 6, 9, 15 and 18 into their prime factors:

2. Finally, you need to choose the commons and non commons with their greatest exponents and multiply them. Then you get:

Therefore, it will take 90 Earth years for them to all line up.
2x - 5y = -10
5y = 2x + 10
y = 2/5x + 2
Equation of a line is given by y = mx + c; where m is the slope.
Therefore, the required slope is 2/5
Answer:
-12 and -20
Step-by-step explanation:
(3x+4)+x=-32
4x+4=-32
4x=-36
x=-12
the other: -32-(-12)=-20
hope it'll help!
