Answer: a = 6
Step-by-step explanation:
The slope of the line is -1/2 so if y = -4, x = 6. In your case, x is a.
Hope this helps!
3(x-2)>-3 means 3x-6>-3 so now add 6 for the both sides and it will be 3x>3 now div by 3 so the answer is x>1 .. I hope that would help ya !
The rules are very simple: an angle is acute if it's less than 90°, whereas it is obtuse if it's more than 90°.
So, for the first task, you just need to compare the given angle with 90°. If the angle is less than 90°, it's acute. Otherwise, it's obtuse.
Moving on, angle B is complement of a angle A if A+B=90. So, for example, the complement of the first angle is 80, because 10+80=90. Note that this implies that obtuse angles don't have a complement.
Finally, angle B is supplement of a angle A if A+B=180. So, for example, the complement of the first angle is 170, because 10+170=180.
Answer:
The mode, which is 7, is not a typical distance for the data. The median, which is 3.5, is not a typical distance for the data. The mean, which is 4, is a typical distance for the data. So, Grace’s reasoning is not correct.
