Answer:
s = 2/3t
Step-by-step explanation:
For some time (t) in minutes, Sarah can iron "s" shirts:
s = (12/18)t
s = 2/3t
_____
If you need to, you can start with a proportion:
shirts/minutes = s/t = 12/18
Then multiply by t to get the above equation.
Answer:
-271

Answer:
x=3
Step-by-step explanation:
2(x+1)=x+5
Use the distributive property to multiply 2 by x+1.
2x+2=x+5
Subtract x from both sides.
2x+2−x=5
Combine 2x and −x to get x.
x+2=5
Subtract 2 from both sides.
x=5−2
Subtract 2 from 5 to get 3.
x=3
Answer:
You gave the explicit form.
Step-by-step explanation:
You gave the explicit form.
The recursive form is giving you a term in terms of previous terms of the sequence.
So the recursive form of a geometric sequence is 
and they also give a term of the sequence; like first term is such and such number. All this says is to get a term in the sequence you just multiply previous term by the common ratio.
r is the common ratio and can found by choosing a term and dividing by the term that is right before it.
So here r=-3 since all of these say that it does:
-54/18
18/-6
-6/2
If these quotients didn't match, then it wouldn't be geometric.
Anyways the recursive form for this geometric sequence is
