The quotient of x and 7 is less than or equal to-25

x/7 ≤ -25

x  ≤ -175

Step-by-step explanation:

Quotient means division

x/7 ≤ -25

Multiply each side by 7

7*x/7 ≤ -25*7

x  ≤ -175

The absolute value gives the positive value of any given number inside the symbol. The absolute equation is,
 
                 2.5 = I d - 2I

The values of d can be calculated through,
      2.5 = d - 2 
          d = 4.5

Also,
     -2.5 = d - 2
      -2.5 + 2 = d 
      d = -0.5

Thus, the maximum value of the temperature is 4.5 and the minimum value of the temperature is -0.5.
