As an expression, it would be:
3 - 1/13w (or you could also do 1/13w - 3).
Not positively sure but I believe it goes like this
Answer: 9x+26+5x=180
14x+26=180
180-26=14x
14x=154
X=15
X^2-5x+5x-25 (multiply (x-5) with (x+5))
X^2-25 ( -5x+5x =0)
Answer:
$48.5
Step-by-step explanation:
Given data
Number of purses= 14+2= 16
Cost of 14 purses= $50
Cost of 2 purses= $38
Let us use the weighted cost method
Mean cost = (14*50+ 2*38)/16
Mean cost = (700+ 76)/16
Mean cost = 776/16
Mean cost =$48.5
