X = 7.............................
3.124
3 + 0.100+ 0.020 + 0.004
Use substitution when either and x or y is given, for instance: x = 2y + 3 or y = 8x - 9.
Use elimination when a number from both equations can cancel each other out, for example:
2x + 3y = 19
-2x + 7y = 12
Hope this helps!
Answer:
With F represent the variable of interest:



Step-by-step explanation:
For this case we have a normal limits for the temperature Range. The minimum is 660 F and the maximum 790 F.
We can find the midpoint of this interval like this:

And the difference between the midpoint and the limits are:


So then we can create the following inequality:
With F represent the variable of interest.:



Answer:
-15/16
