Answer:
In 10 years from now Violet's age will be 27 years old
Step-by-step explanation:
Let
x ----> Ben's age
y ---> Violet's age
we know that
Ben is 5 years older than Violet
so
----> equation A
After eight years, Ben's age will be 1.2 times of Violet's age at that time.
so
----> equation B
substitute equation A in equation B
solve for y
Find the value of x
therefore
Ben's age is 22 years now
Violet's age is 17 years now
How old will Violet be 10 years from now?
Adds 10 years to Violet's age now
so
[scomposition of 45]
[9 = 3^2, must use this notation (not 3*3)]
[We appy one of the proprieties of square roots]
[now we semplify: we must take out as much as possible all the elements under roots]
[to do that, we must divide the esponent of each element with the index of square roots (2)]
so
, 2/2 = 1
, 1/2 = 0 with 1 of rest
, 5/2 = 2 with 1 rest
[well, after do that, we can take out the elements under tbhe square roots!]
The quotient of each division is the esponent of the element out of the root
The rest of each division is the esponent of the element under the root
so:
(quotient = 1, see the first operation) *
(rest = 1, see the second operation) *
(quotient = 2, see the third operation) *
(rest = 1, see the third operation)
The final result is:
3 (=3^1) * a² * √5 * √a
3a²√5a
It's more intuitive and easy, but the explanation (necessary) is very long. If you have other questions, ask me here in the comments! Also sorry for my english, not so good!
