(Math Integers) Show work please thank you!

18-(-13)=31

Step-by-step explanation:

Since -13 is a negative number, you add 13 instead of subtracting 13.

I didn't explain it very well but I hope it helps.

is there any photos or whatever?

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
