A washer and a dryer cost $799 combined. The washer costs $49 more than the dryer. What is the cost of the dryer?
rusak2 [61]
A) w + d = 799

w -49 = d
dryer = 424 -49
dryer = 375

Okay so- im really stuck (help is well appreciated)
Minchanka [31]

Answer:

Step-by-step explanation:

The equation is x<= 5.

So 5 and all the numbers less than 5 would be an answer for x.

So you would put a closed dot on 5, because x can equal 5. Then put a line pointing right to all the numbers less than 5.
