F + s = 10
| f - s | = 18
-------
This means that:
f = 10 - s
And also that:
| f - s | = 18
(f-s)²=18²
f²- 2sf + s² = 324
But f=10-s
So...
(10-s)² - 2s(10-s) + s² = 324
(10-s)(10-s) - 20s + 2s² + s² = 324
100 - 20s + s² - 20s + 2s² + s² = 324
4s² - 40s + 100 = 324
4s² - 40s + 100 - 324 = 0
4s² - 40s - 224 = 0
1/4 * (4s² - 40s - 224) = 1/4 * 0
s² - 10s - 56 = 0
(s-14)(s+4)=0
So s can be either 14 or -4.
When s = 14, f = -4.
When s = -4, f = 14.
Answer: Anna = and Bailey =
Step-by-step explanation:
Since we have given that
In case of Anna:
Number of cups of lemonade concentrate = 2
Number of cups of water = 3
So, Part of concentration for Anna would be
In case of Bailey:
Number of cups of lemonade concentrate = 3
Number of cups of water = 5
So, Part of concentration for Bailey would be
Hence, Anna = and Bailey =
