x < - 
add
to both sides
- 3x >
+ 
- 3x >
( divide both sides by - 3 )
note that when we divide/ multiply by a negative quantity we must reverse the inequality symbol
x < - 
1 joule = 6,242e+18ev
20 joule = 20 joule *6,242e+18 ev/joule =1,248e+20 ev
1,248e+20 ev / (10 ev / photon) =1,248e+19 photons.
Answer:
57
Step-by-step explanation:
How I did this was 513 divided by 9 so the equation that I did was 513/9.
Since we know the value for c and d we just plug them into the equation which will look like this. 6•5^2-5•4+8
