Answer:
The area of A is nine times the area of B.
Step-by-step explanation:
4 x 1/5 so (1x4)/5 so the answer is 4/5 or .8
Answer:
8x + 5x = 13x
Step-by-step explanation:
Since these two can be added, you just add like normal and make sure you do not forget the x.
3x+17-5x=12-(6x+3)
-2x+17=12-6x-3
-2x+17=9-6x
17=9-4x
8=-4x
x=-2
Since the average height is 60 inches and its deviation is 2 inches, one deviation to the right (or higher) is 62 inches (60 + 2). Two deviations is 64 inches, three deviations is 66 inches, and four deviations is 68 inches.
Since the average weight is 100 pounds and its deviation is 5 inches, we repeat the process from finding heights to get to 115 pounds. That takes three deviations.
The MORE deviations away, the more unusual it is. So the height (4 deviations) is more unusual than the weight (3 deviations).
