-- there is an equation to find this: (2n + 1) + (2n + 3) = (whatever number is given as their sum)
use the equation: 2n + 1 is an odd interger, 2n + 3 is the next odd integer.
(2n + 1) + (2n + 3) = 88
add like terms.
4n + 4 = 88
4n = 84
n = 21
now plugin.
2(21) + 1
42 + 1
= 43 (the first odd integer)
this means the second one would be 45.
answer: 43 and 45
add them to check:
43 + 45 = 88

Answer:
Answer: 45
Step-by-step explanation:
Of the possible numbers (1,2,3,4,5,6), 3 are greater than 3. The probability to roll a number greater than 3 is 3 over the 6 total. That can be simplified to 1/2 for the probability. If she rolls the dice 90 times 90 x 1/2 or 45 rolls will receive a number greater than 3.
You can make 3 and 3/7 into a improper fraction as 24/7 by multiplying 7 by 3 which is 21 and then adding that to 3 which gives you to answer 24/7. To find the reciprocal you simply flip the fraction which gives you 7/24
