Julies ratio of laps to minutes is 4 to 9. how many laps will Julie run in 36 minutes?

24 laps

Step-by-step explanation: it’s a ratio, so a fraction. 4/6 = x/36

cross multiply and get 6x = 144

divide by 6 and get x = 24

tube or goog would be a great resource to with that question

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
