Answer:
10 years old
Step-by-step explanation:
Let's say the age of the younger sister is x. Then the age of the older sister must be x + 2 because the ages are consecutive <em>even</em> numbers.
"Twice the age of the youngest exceeds the oldest by 8" means that we multiply x by 2 and set that equal to (x + 2) + 8:
2x = (x + 2) + 8
2x = x + 10
x = 10
So, the youngest sister is 10 years old.

that is in order. follow these and you should figure it out yourself :)
Similarities:
Have a consistent change for every interval can be represented as functions of a variable points lie on a line.
Differences: linear equations represent all solutions to all x values, whereas arithmetic sequences pick integer spacing
Answer:
The "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56.
