Which expressions are equivalent to 3(6+b)-(2b + 1)?
Anna [14]

Answer:

18+3b-2b-1

b+17

Step-by-step explanation:

\mathrm{Using\:the\:distributive\:law}:\quad \:-\left(a+b\right)=-a-b

-\left(2b+1\right)=-2b-1

=3\left(6+b\right)-2b-1

=18+3b-2b-1

\mathrm{Group\:like\:terms}

=3b-2b+18-1

\mathrm{Subtract\:the\:numbers:}\:18-1=17

=3b-2b+17

\mathrm{Add\:similar\:terms:}\:3b-2b=b

=b+17

PLEASE HELP ME!!! I have no idea what to do-
Stells [14]

Your answer would be the last option, D.

This is because spinning the spinner does not affect which marble you pick, as these are mutually exclusive events. This means that if the spinner lands on red, you could choose a black or white marble, and if the spinner lands on green you could also choose a black or white marble.

The only sample space that represents this is D because it's the only one that includes both black and white options after spinning red and green.

I hope this helps!
