For A the answer is 85% correct. Then 15% incorrect. I got the number correct by taking 68 and dividing by 80. To get the number incorrect I took the 15 other questions (80-68) and did 12 divided by 80 to get the 15% incorrect.
Just plug in the numbers for the variables
Does this help?
Answer:
I think it's x > -5
Step-by-step explanation:
I think it's this because the dot starts at the 5 and points towards the 11. 11 is a bigger number than 5, the x is 11. The <u>> </u> means when something is grouped together and in this case, nothing's grouped together.
Answer: Sure what you having trouble with?
Step-by-step explanation:
I think the easiest way to think about this is to put 0.25 into fractional form. 0.25 = 1/4 because 4 divided into 1 = 0.25
So 1/4 added to 2/9 will give us a fraction (rational number). Of course to determine what the fraction is, we have to get a common denominator.
(In case you wanted to know what that rational number is: The least common denominator would be 36. So changing 1/4 by multiplying top and bottom by 9 gives 9/36 and changing 2/9 by multiplying top and bottom by 4/4 gives 8/36 and adding 9/36 to 8/36 gives 17/36 - a rational number.)
