Three hundred ten million, seven hundred sixty three thousand, one hundred thirty six
Answer:
18/8 and 9/4, 4/7 and 10/17.5: PROPORTION.
2/3 and 9/12, 7/5 and 27/20, 3/8 and 6/141: NOT A PROPOTION :) Hope this help
Step-by-step explanation:
Since 325 is a whole number, then the denominator is 1.
So:
325 as a fraction is: 325/1
Distribute the 5x to both the 4x and the 3 to get
20x^2+15x=24
Move the 24 over to get
20x^2+15x-24=0
This can't be factored so we must use the quadratic formula, (-b+-sqrt(b^2-4ac))/(2a)
Plug in to get
(-(15)+-sqrt((15)^2-4(20)(-24)))/(2(20)) => (-15+-sqrt(225+1920))/40 => -3/8+-sqrt(2145)/40
Final answer:
X=-3/8+sqrt(2145)/40 or x=-3/8-sqrt(2145)/40
Ugly problem. Hope I could help :)
