5x + 10y = 50
x + y = 8
x = 8 - y
5*(8-y) + 10y = 50
40 - 5y + 10y = 50
10y - 5y = 50 - 40
5y = 10
y = 2
x + y = 8
x + 2 = 8
x = 8 - 2
x = 6

Answer:
The given expressions simplifies to tan (4x).
Step-by-step explanation:
Here, the given expression is :
By TRIGONOMETRIC IDENTITY:
Putting this identity here, and taking A = 9 x, B = 5 x, we get
= tan(4x)
Hence, the given expressions simplifies to tan (4x).
Answer:
Abebe will be exact twice as old as Aster in 8 years.
Step-by-step explanation:
Since Abebe is 12 years old, and his sister Aster is 2 years old, there is a difference of 10 years between them (12 - 2). Therefore, the difference between the two implies that Abebe is exactly twice as old as her sister when she is 10 years old, and she is 20 years old (10 x 2 = 20).
Therefore, since 20-12 equals 8, Abebe will be twice as old as her sister Aster hers in 8 years.
