I would have to say false because they do not have the same perimeter and area
Answer:
Michelle must get an 80 on her next test to keep her average score.
Step-by-step explanation:
Since Michelle got an average score of 80 on two tests, to determine what score she must get on the third test so that her average score for the three tests is the same as the average score for the first two tests, the following calculation must be performed:
X / 2 = 80
X = 80 x 2
X = 160
X x 3 = 80 x 3
X x 3 = 240
X = 240/3
x = 80
So, Michelle must get an 80 on her next test to keep her average score.
The answer is B. And I am not that sure about my answer, but it has to be the correct answer for what you put. THANK YOU!!!!
The problem is a irrational number
1.25x
because 25% can be represented as 0.25. so as the new price would be 125% of the old one its 1.25x
