To fit in an existing frame, the length, x of a piece of glass must be longer than 12 cm but not longer than 122 cm Which inequality can be used to represent the lengths of the glass that will fit in the frame?
12 12x5122
O x > 12 or x5122
O x< 12 or x 5 122

it's

so, converting firstly the mixed fractions to improper fractions and then "adding".

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  

x

​    

=240

=48
