(2x+23)+(9x-5)=95
11x+18=95
x= 95-18/11
x=7
therefore substituting value of x in the given equations of angles:
angle ABD = 2(7)+23=37°
angle DBC = 9(7)-5= 58° Answer
to verify = 37°+58°= 95° ( which was given)
Answer: D

The amount that Tony and his friend's will spend at the dell can be found by
writing an expression for the total cost.
<h3 /><h3>Response;</h3>
- The amount that they spent at the dell is <u>$16</u>
<h3 /><h3>Method used in finding the amount that was spent;</h3><h3>Given;</h3>
The number of Toby's friends = 3
Number of people that ate lunch, n = Toby + His friends = 1 + 3 = 4
The cost of the sandwiches and drinks
![\begin{tabular}{|c|c|c}Item&Cost(\$)\\Sandwich&2.75\\Drink &1.25\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%7B%7Cc%7Cc%7Cc%7DItem%26Cost%28%5C%24%29%5C%5CSandwich%262.75%5C%5CDrink%20%261.25%5Cend%7Barray%7D%5Cright%5D)
<h3>Solution;</h3>
The expression that gives the amount Toby and his friends spend altogether is therefore;
Amount spent = n × (Cost of a sandwich + cost of a drink)
Which gives;
4 × (2.75 + 1.25) = 16
- The amount Tony and his friends spent is<u> $16</u>.
