What are 7 yards 2 feet 8 inches + 4 yards 3 feet 7 inches plz show your work and i will make you brainliest

First I will add the 7 and 4 yards. This gives us 11 yards. Next, we will add the feet, which gives us 5 feet. Finally, we will add the inches, and adding both gives us 15 inches.
Now, we will convert the inches into 1 foot and 3 inches. Now we have 11 yards, 6 feet, and 3 inches. Since we know a yard is approximately 3 feet, we can convert those to two yards.
Now we have 13 yards and 3 inches.

A: 18/15b : 7 - -8 = 15 , 12 - -6 = 18 the y variable always goes over the x variables, c : same thing a
