Answer:
2x = 54, 3x = 81
Step-by-step explanation:
135 degrees = 2x + 3x
5x = 135
x = 27
2x = 54
3x = 81
Answer:
-8 < x, the answer is B
Step-by-step explanation:
Since its starting from -8 and your going to the greater side of the numberline teh variable will be greater than -8, whenever the circle is filled it just means greater than or equal to depending on which side its going. If its filled in, it means that its greater than or equal to or less than or equal to depending on which side its going towards.
Reminder:
<--------------- Negative side/Lower -----------------------> Positive side/Greater
Wrong. You can either drive or can't. So if 15 hs students can drive and 15 can not then there are a total of 30 students being surveyed. So there's a 50% chance that they know how to drive.
When she surveyed the college students she surveyed 60, 30 of them knew how to drive. Therefore there's also a 50% chance that the college students know how to drive.
It's wrong because the percentages are both the same.
3 1/5 - 1 4/5 = 1 2/5
you could also convert to a decimal so
3.2-1.8=1.4
and 1.4 in fraction form is 1 2/5
