Answer:
15%
Step-by-step explanation:
The quantities must be in the same units
Using the conversion
I hour = 60 minutes, then
3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.
Thus
× 100% =
= 15%
Which represents the solution set of an any quality 5X-9 greater than 21

Answer:
Step-by-step explanation:
The table shows values of for different values of
.
Let us test each equation with the values given in the table.
Equation 1:
For = 1, we get,
So, we got 1 for . But as per table, value of
should be -5.
So, equation 1 is incorrect.
Equation 2:
For = 1, we get,
So, we got -5 for . It matches with the value of table.
Let us check for another value of in order to confirm.
For , we get,
So, we got -4 for . It matches with the value of table.
So, equation 2 is the correct answer.
We can be completely sure by checking the remaining equations too.
Equation 3:
For = 1, we get,
So, we got -1 for . But as per table, value of
should be -5.
So, equation 3 is incorrect.
Equation 4:
For = 1, we get,
So, we got -7 for . But as per table, value of
should be -5.
So, equation 4 is incorrect.
