Express the relationship 20 < C < 30 in terms of F, where F = 9/5C + 32.
_____________ < F < _____________
To express the relationship 20 < C < 30 in terms of F, we will substitute the values of C into the equation F = (9/5)C + 32.
First, we'll start with the lower limit, 20 < C.
Substituting this value into the equation, we get:
F = (9/5) * 20 + 32
= 36 + 32
= 68
So, the lower limit in terms of F is F > 68.
Now, let's move to the upper limit, C < 30.
Using the same process, we substitute C = 30 into the equation:
F = (9/5) * 30 + 32
= 54 + 32
= 86
Therefore, the upper limit in terms of F is F < 86.
Combining both inequalities, we have 68 < F < 86 as the expression representing the relationship between F and the given range of C.
