How much higher is 500 than 400 m? How much higher is 500 than -400 m?
What is the change in elevation from 8,500 m to 3,400 m?
What is the change in elevation between 8,500 m and -300 m?
How much higher is -200 m than 450 m?

ratio is 2 : 9

the answer is three

13.5 : 3

answer: x=60

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
