Answer:
The cost of the dress is $240.
Step-by-step explanation:
With the information provided, you can use a rule of three to find the total cost of the dress as you know that $60 represents 1/4 of the total cost of the dress:
60 → 1/4
x ← 1
x=(60*1)/(1/4)
x=(60)/(1/4)
x=(60*4)/(1)
x=240/1
x=240
According to this, the answer is that the cost of the dress is $240.
Answer:
x>-9
Step-by-step explanation:
Look at the denominator,
since (x-6)/(x+9) is a fraction,
x+9=0
x=0-9=-9,
so x must be any number greater/larger than -9 in order to let the whole fraction be less than 1.
