Answer:
Step-by-step explanation:
Let x be the amount of dough required for small pizza, y be the amount of dough required for medium pizza and z be the amount of dough required for large pizza.
As per the question , we have
Hence, the equation for the question with the variable representing the amount of dough needed for small pizza.
<em>Hey</em><em>!</em><em>!</em>
<em>Here</em><em>'s</em><em> </em><em>your</em><em> </em><em>answer</em>
<em>7</em><em>+</em><em>(</em><em>-</em><em>7</em><em>)</em>
<em>=</em><em>7</em><em>-</em><em>7</em>
<em>=</em><em>0</em>
<em>so</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>0</em>
<em>hope</em><em> </em><em>it</em><em> </em><em>helps</em><em>.</em><em>.</em><em>.</em>
If you type the equation into y1 on your calculator and use the table graph you get coordinates that you can graph. ( 0,-9 ) ( 1,-6 ) ( 2, -3 ) ( 3 , 0 ) ( 4, 3 ) ( 5 , 6 ) ( 6 , 9 ), just graph those and that should answer your question :)
The unknown number would be 11
738 + 164 = 902
902 / 82 = 11
Ans: 11
