I believe the correct given equation is in the form of:
4 – 0.25 g + 0.5 h
Now we are to evaluate the equation with the given values:
g = 10 and h = 5
What this actually means is that to evaluate simply means
to calculate for the value of the equation by plugging in the values of the
variables. Therefore:
4 – 0.25 g + 0.5 h = 4 – 0.25 (10) + 0.5 (5)
4 – 0.25 g + 0.5 h = 4 – 2.5 + 2.5
4 – 0.25 g + 0.5 h = 4
Therefore the value of the equation is:
4
It is approximately 1.000
This ratio is in a form of dogs:cats.
The ratio given means there are 3 dogs for every 2 cats.
You can rewrite it as 3 dogs:2 cats.
If there are 30 cats, you would write the ratio as x dogs:30 cats.
Since the same must be done to both sides, you must find how many times 2 was multiplied to get 30 then multiply dogs by that number.
30 / 2 = 15
3 • 15 = 45
So if a shelter has 30 cats, then it has 45 dogs.
This can be written in a ratio as 45:30, or 45 dogs:30 cats.
What is the digit at the hundred thousands place? It is 2. Is the digit to the right of it less than 5? No, 5 is 5. So replace the digits to the right of 2 with 0, and change the 2 to 3.
