D.180+x=7x
x-7x=-180
-6x=-180
x=180/6
x=30 pounds
180+30=210

Let daughter's weight = x
A father and his daughter together weigh seven times the daughter's weight = 7x
sum of the weight = 180 + x
Therefore, the expression would be 180+x = 7x, OPTION D.
Hope this answers the question. Have a nice day.
