is this on that paper too?

anonymous · Answer

no

anonymous · Answer

damn
does it say point B is half way between  A and C

anonymous · Answer

oh nvm, it is the same as the last one

anonymous · Answer

anonymous · Answer

$$AC=AB+BC$$
$$3x+3=-1+2x+11$$ solve for $x$

anonymous · Answer

lazy math teacher with dull, dumb algorithmically generated questions from kutasoftware
ought to be ashamed

anonymous · Answer

you need help solving that for $x$ ?

anonymous · Answer

yes

anonymous · Answer

combine like terms, get 
$$3x+3=2x+10$$ subtract $2x$ get 
$$x+3=10$$ then subtract $3$ to get $x=7$

anonymous · Answer

then plug that back in to $3x+3$ to get 
$$3\times 7+3=24$$

thank you so much!!!!
