1/4(12) + 1/2(− 6)
3 - 3
0
To find how small is 0.5 than 5, you can just subtract them.
5 - 0.5 = 4.5
Hence, 0.5 is 4.5 much smaller than 5.
The probability that an event occurs is the number of times it could occur compared to the total number of possible events, assuming the probability of each event occurring is equal.
John has
coins total. If 4 of the coins are dimes, the probability that he draws a dime is

Answer:
39/37 and 6/5
Step-by-step explanation:
To start, let's assume that 9-8x is positive (we will do this to get rid of the absolute value, but then check later). We get 9(9 - 8x) = 2x + 3, or 81 - 72x = 2x + 3, so 74x = 78 and x = 39/37. If we assume 9-8x is negative, the |9-8x| will turn into 8x-9, so we get 9(8x - 9) = 2x + 3, or 72x - 81 = 2x + 3 , so 70x = 84 and x = 6/5. If we plug the values back in, 9-8(39/37) needs to be positive, which works, and 9-8(6/5) needs to be negative, and this works, so the answers are 39/37 and 6/5.
The relation between the numbers is 2:5 so it would be 2x and 5y and you plug in the numbers. When x=42 which is 2(21) then y would be 5(21) which equals 105 :-)
