Total play = 20
Nancy win = 12
Ratio would be: 12/20 = 6/10 = 3/5
So, your answer is 3/5
I think what you are looking for is 5x=300 therefore x=60 so at 60cars he would start to make more.
Use the Pythagorean Theorem of a² + b² = c² to solve for x.
x² + (x + 3)² = (√117)²
x² + x² + 6x + 9 = 117
2x² + 6x + 9 = 117
2x² + 6x + 9 - 117 = 0
2x² + 6x - 108 = 0
2x² + 18x - 12x - 108 = 0
2x(x + 9) - 12(x + 9) = 0
(2x - 12)(x + 9) = 0
x = - 9, 6
Length cannot be negative so you can't use - 9.
x = 6. Option C is your answer.
Answer:
A got 243 tk
Step-by-step explanation:
Supose the amount C got was "x"
12 times B's share is 6 times C's share, that would be:
B = 6x
Also, 8 times A's share is 12 times B's share, that would be:
8A = 12B
8A = 12(6x)
8A = 72x
A = 72x/8
A = 9x
Now, we can say:
A = 9x
B = 6x
C = x
We know total is 432, thus we can write and solve for x first:
A + B + C = 432
9x + 6x + x = 432
16x = 432
x = 432/16
x = 27
A got "9x", so plugging in x = 27, we know:
A got 9*27 = 243 tk
