Answer:
(8)(21) = 12x
Step-by-step explanation:
(8)(12) = 21x
(8)(21) = 12x
(12)(8) = 12x
(12)(21) = 8x
Opposite : Adjacent
12 in : 21 in
Opposite : Adjacent
8 in : x in
Equate both ratios to solve for x
12 : 21 = 8 : x
12 / 21 = 8 / x
Cross product
(12)(x) = (21)(8)
12x = 168
x = 168 / 12
= 14
x = 14
If you square root 124, you get 11.13552872566004.
If you square that you'll see that that is the correct answer.
Answer:
Let total number of boys be b.
ratio of boys after 14 boys leave is
(b - 14) / p = 3 / 10
=> 3 p = 10 b - 140
=> 10 b = 3 p + 140
= > b = 0.3 p + 14
The answer would be D. -11i and 11i
