Answer:
From my thinking prospection the answer should be 18....
Answer:
140, 60
Step-by-step explanation:
15x+5 + < CDB =180 line form an 180 angle
180-80-6x-6 = < CDB sum of angles in a triangle is 180
substitute < CDB from second to first
15x+5+180 -80-6x-6 =180
combine like terms
9x -81 =0
x=81/9=9
so angle YDC = 15*9+5 = 140 degrees
and angle DBC = 6*9+6= 60 degrees
Answer:
The solution to the inequality is:

Please also check the graph of the solution to the inequality.

Answer:
Marisa has made 6 sandwiches.
Step-by-step explanation:
The pounds of roast beef required to make each sandwiches is
, and not
as erroneously typed in the question.
Given that each deli sandwiches made, uses
pounds of roast beef.
Marisa started with 5 pounds, and had 2
pounds left.
Thus,
pounds of roast beef used = 5 - 2
= 5 - 
= 
= 
= 2
Marisa had used 2
pounds of roast beef. So that;
the number of del sandwiches made = 2
÷ 
=
÷ 
= 6
Therefore, the number of sandwiches made by Marisa is 6.
