To save time, you dont need to write "> or ="
You can simply write ">=" without the quotes.
So 3x >= 10 means "3x is greater than or equal to 10"
-----------------------------------
we start with 3x >= 2x+5
we want 3x-10 on the left hand side. We already have a 3x. So if we stick a -10 on the left side, we need to do the same thing to the right side to balance things out. We can subtract 10 from both sides to do this
3x >= 2x+5
3x-10 >= 2x+5-10 ... subtract 10 from both sides
3x-10 >= 2x-5
So it looks like a 5 will go in the blank because the negative portion is already taken care of.

Answer:
the answer is B ;]
Step-by-step explanation:
The required number would be 80 which is 24.5% equal to 19.6.
The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Misha obtained a score of 67% on her exam, that corresponds to 67 out of 100. It is expressed as 67/100 in fractional form and as 67:100 in ratio form.
Let the required number would be x
To determine the required number 24.5% represents as a fraction, you can divide 24.5 by 100. This gives you 0.245.
To find out required number 19.6 is 24.5% of, you can set up the following equation:
19.6 = 0.245x
To solve for x, you can divide both sides of the equation by 0.245:
x = 19.6 / 0.245
x = 80
Therefore, 19.6 is 24.5% of 80.
