Answer:

Step-by-step explanation:

To divide the form directly in fraction divide the numerator and denominator by a common number to simplify the values.
Simplifying the value
Removing the decimal in the numerator makes 1000 in denominator

dividing by a common value i.e 2

Now, removing the decimals from denominator puts the decimal in the numerator gives 
2.33 is the aprox number we start off with. if we got to find the original, we divide 560 by (7/3).
after we estimate the divisior we get 240. 560 - 240 gives us 320.
the answer could be 320.
Half an hour everyday means she exercises 30 minutes per day.
5 hours is 300 minutes. 300/30= 10 days of exercise.
The hole is x+4=0 because (x+4) is canceling out so the hole x=-4

Answer:
Simplifying
4x + -3y = 20
Solving
4x + -3y = 20
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
4x + -3y + 3y = 20 + 3y
Combine like terms: -3y + 3y = 0
4x + 0 = 20 + 3y
4x = 20 + 3y
Divide each side by '4'.
x = 5 + 0.75y
Simplifying
x = 5 + 0.75y
