Ana tinha um recipiente que, cheio de leite, pesava 1,2kg. após consumir 3/5 do leite desse recipiente, ela verificou que restava 840g. qual será o peso desse recipiente quando restar apenas 1/3 de leite?

susie has 7 apples

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  

x

2

=240
