Each day, 30 cents are added onto the fee.
-3 days would mean -3 * 30 cents on the fee, which is -90 cents, or -0.90.
and -2.5 charges of 30 cents would be -75 cents!
...but you can't have negative days or fees, so A and B are out of the question.
4.5 charges of 30 cents IS $1.35...
...but the library charges by day, of course.
8 charges of 30 cents would be $2.40, and both of these are realistic possible numbers.
<span> the value of x is
2(3x+6+2x-4)=94
6x+12+4x-8=94
6x+4x=94-12+8
10x=90
x=9
</span>
The correct option is B): "<span>Let x = 1st integer. Let x + 2 = 2nd integer.</span><span>"
Given that "The sum of two consecutive odd integers is 28."
Now the difference between two odd numbers is 2.
So this means that one odd number has to be greater than the other by 2.
Let the smaller number be 'X' therefore the bigger number will be 'x+2'
thus
x + (x+2) = 28
therefore,
x + x + 2 = 28
now we subtract "2" from both the sides
therefore,
2x = 26
now dividing throughout by 2 we get:
x = 13
therefore,
x + 2 = 13+2
= 15
therefore, the numbers are
13 AND 15</span>
A unit is used as the standard of measurement.
