A bookstore sells books. Paperpack books cost $2 while hardback books cost $6. The store sold 50 books totaling $164. How many hardback books were sold? *

16

Step-by-step explanation:

6x + 2(50-x)=164

6x + 100-2x=164

4x + 100=164

4x=64

x=16

I hope this helps :)

I hate to ask for this but no one gives out Brainliests anymore and I need one

the square root of what number? if you add that, then someone will probably answer the 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  

x

2

=240

=48
