The Dolphins football team gained 16 yards on their first play, then lost 11 yards on the next play. Write an addition expression to represent this situation. Find the sum and explain its meaning.
Answer: On the first play, Dolphin's football team gained 16 yards.
On the 2nd play, Dolphin's football team lost 11 yards.
Therefore, the addition expression to represent this situation is:

The sum of this expression is:

Therefore, we can interpret it as: Dolphin's football team gained 5 yards over the 2 plays
For finding difference or sum of unlike fractions ( fractions with different denominators) then we need to make their denominators same ...so for that we take their denominators LCM ...
7/4 - 1/8 (LCM of 4 and 8 is 8)
=> 7/4 X 2 - 1/8
=> 14/8 - 1/8
= 13/8 ..
Hope it helps !!!
I'm pretty sure it's 73x100/85 if you simplify

Road the situation abroad from shirts at the store for $9 each,
=> received 25 dollars discount
=> paid $88 dollars in total.
=> 88 + 25
=> 113 dollars
Now, let’s find the number of shirts that Dina had.
=> 9 price of shirts * 12 shirts
=> 108 total amount of 12 shirts.
=> 108 – 25 discount = 83.
Thus, the total amount to be paid must be 83, not 88.
=> 88 – 83 = 5, the amount is wrong </span>
