-d has to be 3
think of it as an inverse operation. d is equal to -3 while -d is equal to 3
#2. 32 3/4 - 12 1/2 =
= 32 3/4 - 12 2/4 =
= 20 1/4
#3. 517 37/ 50 + 312 3/100 =
= 517 74/100 + 312 3/100 =
= 829 77/100
#4. 632 16/25 + 32 3/10 =
= 632 32/50 + 32 15/50 =
= 664 47/50
#5. 421 3/50 - 212 9/10 =
= 421 3/50 - 212 45/50 =
= 208 4/25
What i would do is multiply $7500 by 10. because it asks what his account will be worth in 10 years so just multiply $7500 by 10.
I don’t feel like solving it right now but in order to find a mean you have to add up all numbers and divide by the amount of people/objects.
If you want to solve this problem you would need to multiply 13 by 5 and then add 12, 16, 14, and 8 together and subtract it from your product of 13 and 5.
After that just check your answer by seeing if the mean of all the numbers is the same.
