If a car travels at a speed of 25 mi/h for t hours, then travels 45mi/h for m hours, what does the expression 25t+45mi represent

The expression represent the distance that car traveled.

Velocity= Speed/Time meaning that  Speed= Velocity x Time

 (25t + 45m) miles

The expression above represents the distance that the car travelled.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

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
