I think it is option 1 sorry if wrong
Answer:
Because 16 inches is one foot and 4 inches, as there are 12 inches in a foot. So this one foot is added to the 7 inches. Or otherwise we can say: a hundred inches (100 in).
Step-by-step explanation:
If we tell the length in feet, only the rest of the integer number of feet is expressed in inches.
9q-4=3r-6
+4=+4
9r=3r-2
9/9=3r-2/9
r=3r-2/9
4(x-y)
4x-4y^10
