Answer:
As a decimal your answer: is 5.4 rounded to the nearest tenth. As a mixed number fraction your answer is: 5 11/25. As a improper fraction your answer is: 136/25.
Step-by-step explanation:
Basically what I did was just divide 6.8 by 4/5. Or you could change 4/5 in a decimal and divide like that, OR change 6.8 into a fraction which is what if did- I’ll show you below. But, it’s better to have all solutions to the problem.
1) change 6.8 into fraction: 34/5
2) rewrite: 34/5 divide by 4/5
3) multiply: 136/25
4) alternative forms:
A. Mixed number- 5 11/25
B. Decimal: 5.44 or 5.4 rounded to nearest tenth.
I hope this helped, good luck! :)
Answer:
The southern asia are includes Afghanistan, India, Pakistan, Bangladesh, Sri Lanka, Nepal, Bhutan and Maldives as the constituent countries.
hope this helps as the south of asia is hard to describe, that is why I included a map.

so h = 7, k = -2, meaning the vertex is at (7, -2).
the squared variable is the "y", meaning is a horizontal parabola.
the "p" distance is negative, for a horizontal parabola that means, it's opening towards the left-hand-side.
we know the focus and directrix are "p" units away from the vertex, and we know the parabola is opening horizontally towards the left-hand-side.
the focus is towards it opens 1 unit away, at (6, -2).
the directrix is on the opposite direction, 1 unit away, at (8, -2), namely x = 8.
