-10x=-12x + 21 + 11
-10x= -12 + 32
-10x + 12x = 32
2x = 32
X = 32/2
First make 20 into a fraction, then solve; 3/5 · 20/1. 60/5 = 12. Hope that helps!
Answer:
log₃(243) = x
Step-by-step explanation:
3^x = 243
Rule: a^x = b -> logₐ(b) = x
log₃(243) = x
the number is 6 so we round up to 9.7 s
I hope that help .
