Answer:
7 cookies
Step-by-step explanation:
We have 3 brothers
First , Second, Third
Let the total number cookies be represented by A
1 cookie = 1
Working backwards, we start from the third brother
If we work backwards
It means he gave everything away
We start from the youngest
He was given 1/2 of what was left and 1/2 a cookie
This means,
1/2 + 1/2 = 1
The second brother
He got half of what is left and 1/2 a cookies
Half of what is left from brother
= What the youngest brother got + 1/2 + 1/2 a cookie
= 1 + 1/2 + 1/2
= 1.5 + 1/2
= 2 cookies
For the first brother
He got 1/2 of the cookies + 1/2 cookie
= 1.5 × 2 + 1/2 + 1/2 cookies
= 3 1/2 + 1/2
= 4 cookies
The first brother got 4 cookies
The second brother got 2 cookies
The third broth got 1 cookies
Answer:
(A) 24 and 66
Step-by-step explanation
Complementary angles add up to 90 degrees
Supplementary angles add up to 180 degrees
(A) 24 + 60 = 90
These 2 angles sum to 90, so therefore they are complementary
(B) 56 + 124 = 180
These 2 angles sum to 180, so they are supplementary, not complementary
(C) 34 + 66 = 100; 34 + 56 = 90
While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question
(D) 56 + 124 = 180; 66 + 114 = 180
Both of these angle pairs are supplementary, so they do not satisfy the answer to the question
Answer:4/7
