(01.04 mc)the elevation of city a is 72 feet above sea level; the elevation of city c is 24 feet above sea level. the elevation of city d is 1 over 4 of the elevation of city c. part a: write an expression to represent the elevation, in feet, of city d. part b: simplify the expression and explain why the answer is negative or positive.

exactly you go it

step-by-step explanation:

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
