Question 74570
1) Translate into algebraic expression.
   The Difference between five times the input and seven.
Let the input be "x":
5x-7
-------------

2) six times the input, added to 8
6x+8
-----------------

3) Solve the problem
  Write a symbolic rule that represents the relationship in which the output variable t is 5 more than 3.5 times the input variable r.
t=3.5r+5
----------
 What is the input corresponding to an output value of 26?
t=3.5*26 +5
t = 91+5 = 96
-----------------

4) Write a symbolic rule that represents the relationship in which the output variable t is 7 more than 2.5 times the input variable r.
t = 2.5r+7
-----------------
 What is  the corrisponding to an input value of 8?
t = 2.5*8+7 
t = 27
-----------------
