Answer:
X=12
Step-by-step explanation:
simplify both sides of the equation then isolate the variable.
5/2(12)-7=23
3/4(12)+14=23
making both equations equal to each other.
Let's say that you're in your room and you find that the current temperature of 72 degrees is too cold, so slowly you increase the temperature of the room by two degrees.
We know that the explicit formula is
a^n=a^1+ (n-1)d
and so by substituting the given information in
a^n= 72 + (n-1)2
a^1=Initial temp
d= rate of change
by substitution a value of n (the term we are looking for) into this equation, you can then calculate the temperature that you just set the room too.
