Let t be the number of tulips. Which algebraic sentence would help you figure out how many tulips Latonya bought? Select one of the options below as your answer:
A. t + 2(t + 3) = 45
B. t + 2(t – 3) = 45 
C. 2t (t + 3) = 45
D. -3t + 2t = 45

anonymous · Answer

Let r be the number of roses so, we have that.
1t + 2r =45   (1)
and
t=r+3 so
r=t-3   
Now we  just have to substitute that value of r in the ecuation(1) and that will match with alternative B.
We can also solve that sistem of acuations for r and t.
