Afather and his daughter together weigh seven times the daughter's weight x. the father weighs 180 lbs. which equation can be used to find the daughter's weight?

a. 180-7x = x

b. x -180 = 7x

c. 180 -x = 7x

d. 180 + x = 7x

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.
