The probability that the sum of the dice is 7 is 1/2 because there are only three combinations that result in the sum of 7: (1,6)(2,5) and (3,4). But there are 6 possible outcomes( this is if you don’t add reverse combinations such as 1,6 and 6,1) so the probability would be 3/6 or 1/2
We have
3 / (x-5) - x/5
We make the GCF and we have
15/[ 5(x-5) ] - x(x-5)/[ 5(x-5)]
= [ 15 - x(x-5) ] [5(x-5)]
= [ 15 - x^2 + 5x] / [ 5 (x-5) ]
= [15 - x^2 + 5x]/[5x - 25]
An answer to your question is (15-x^2+5x)/(5x-25)
The ratio would be 3:4, or however you write ratios.
Hope this helped! :)
Answer:the third one
Step-by-step explanation: so if you are doing that, it is simple. If it is the power of something, then you go left to multiply, and go right to divide. Then, you will get your answer, but when you are done with that, add then subtract . There, you will find your new answer.
The answer is 1/4. Hope I could help! :D
