Answer:
The equation that can be used to obtain the missing number is (n - 8 )12 = 3 + n
Step-by-step explanation:
The missing number is given as 'n'
The equation that can be used to obtain the missing number is calculated as follows;
(n - 8 )12 = 3 + n
The equation above can be used to obtain the missing number 'n'
The missing number 'n' is calculated as follows;
(n - 8 )12 = 3 + n
12n - 96 = 3 + n
12n - n = 3 + 96
11n = 99
n = 99/11
n = 9
Therefore, the missing number is 9
Answer:
The equation that can be used to find the missing number is 96 - 12n = 3 + n
Step-by-step explanation:
The difference of 8 less a number n
This is 8 - n
Multiplied by twelve
This is:
12(8 - n) = 96 - 12n
Is equal to 3 more than the number.
96 - 12n = 3 + n
The equation that can be used to find the missing number is 96 - 12n = 3 + n

Step-by-step explanation: for #2, look at 6 3/4 and make it into a decimal. Do the same to 7 1/2. Compare them both to see which one is shorter by subtracting 6 3/4 from 7 1/2 and when you get your answer for that, make that into a fraction. Predict that 6 3/4 is shorter because of how much less it is compared to 7 1/2. (I hope I helped you in some way. Good luck!) </h3>
