Amu needs to write a paper that contains more than 3,259 words for school. she had already written 1,271 words and writes at a rate of 284 words per day. which of the following inequalities could be used to solve for x, the number of day it will take amy to finish her paper? a. 284x > 3,259 b. 284x + 1,271 > 3,259 c. 284x > 1,271 d. 284x - 1,271 > 3,259

step-by-step explanation:

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
