Answer:
12-c
Step-by-step explanation:
Let c be Cindy's cookies
Solution:
Each child should have gotten 12 cookies because 96/8 is 12 but Cindy got c less so the answer would be 12-c.
Distribute and combine like-terms!
-4x + 12x - 2x - 2
6x - 2
CE = CD + DE = 2DE + DE = 3DE = 8.7
DE = 8.7/3 = 2.9
CD = 2DE = 5.8
For the inscribed circle, where center is point D. The radius is length DE.
This is because the circle will touch the 3 points where the bisectors intersect with sides of triangle.
radius = 2.9
For circumscribed circle, the center will also be point D. The radius is CD.
The circle will touch 3 points of triangle, A,B,C.
radius = 5.8
Answer:
10/11
Step-by-step explanation:
The fractions already have like denominators so you just add the numerators as there is no need to find the LCM but just in case
