W=4N+10
N+4N+10=90
5N=80
N=80/5=16
Since 36/9= 4
3600/9=400

Answer: A.</h2>
Step-by-step explanation:
<em>Victoria's recipe:</em>
<em />
<em>170g of butter = 250 g of flour</em>
<em />
<em>1 g of butter = 250 ÷ 170 = 25/17 g of flour</em>
<em />
<em />
<em>Daughter's recipe:</em>
<em />
<em>340 g of butter = 400 g of flour</em>
<em />
<em>1 g of butter = 400 ÷ 340 = 20/17 of flour</em>
<em />
<em />
<em>Compare:</em>
<em />
<em>20/17 < 25/17 </em>
<em />
<em>⇒ Daughter uses less flour in her cookies</em>
<em />
<em>⇒ the cookies are more dense</em>
<em>So therefor, the correct answer is A. They have too much butter :) </em>

Answer:
not possible.
Step-by-step explanation:
number of invitations luanne has to address after x days = 120-15x
number of invitations Darius has to address after x days = 120 + 15(7-x)
so, if the number of invitations should be the same for both of them,
we have to equate their number of invitations
120-15x = 120 + 15(7-x)
subtracting 120 from both the sides,
-15x = 15(7-x) = 105 -15x
adding we 15x on both sides, we wont find any solution for x.
so, this isnt possible or the question must be wrong.
