Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9

Answer: B).
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>.
