Answer:
k = 8
Step-by-step explanation:
8(10 - k) = 2k
First, distribute within the parenthesis,
80 - 8k = 2k
Add 8k to both sides of the equation
80 = 10k
Divide both sides by 10 to get your answer
8 = k

Answer:
Two possible sets of answers.
5 men, 11 women and 42 children, or
10 men, 2 women and 88 children
Selamat Sadhya!
Step-by-step explanation:
M = number of men
W = number of women
100-M-W = number of children
Total number of pappadas
5M+3W+(100-M-W)/2 = 100
Solve for W
W = (100-9M)/5 .......................(1)
Examine equation (1).
In order to have W as a whole number, M must be multiple of 5
Therefore M = 5 or 10
If M = 5, W = (100-45)/5 = 11 and children = 100-5-11 = 84
If M = 10, W = (100-90)/5 = 2 and children = 100-10-2 = 88
If x² = 196, then we must do the inverse (square root) to find x. However, the square root of any positive number will always be ± (plus or minus).
That means you have to do:
√196 = x
x = <span>±14.
We can check this by doing:
14 </span>× 14 = 196
-14 × -14 = 196
Therefore the answer is B) -14, 14.
