identical dresses. She knows that she
needs to add 4 inches of lace to the end
of each dress. She has a total of 121 in of
lace to use. Write an equation involving
distributive property that would help
Nalani figure out how many additional
inches, n, of lace she can add to the
dresses. Demonstrate using a model,
as well.

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
