A male polar bear is 2 7/9 meters long. A female polar bear is 1 5/6 long. Sidney thinks the male polar bear is 1 2/3 meters lon ger than the female polar bear. She is incorrect. How did she get that answer?
1 answer:
Answer: See explanation
Step-by-step explanation:
The difference in the length of the polar bear will be:
= 2 7/9 - 1 5/6
The lowest common multiple of 9 and 6 is 18.
= 2 7/9 - 1 5/6
= 2 14/18 - 1 15/18
= 17/18
She is incorrect as she subtracted the denominator from the numerators and didn't find their lowest common multiple. She got the answer this way:
= 2 7/9 - 1 5/6
= (2 - 1) (7-5)/(9-6)
= 1 2/3

Answer:
C. 10–15, 15–20, 20–25, 25–30, 30–35
Step-by-step explanation:
So, to find our x-intercepts, y must be zero
ANSWER: (0,0) (-5.0) (9,0) are your x-intercepts
The answer is c because 2+7=9 and 10-2=8 and 9 is greater than 8 so 2+7>10-2
