Step-by-step explanation:
We know that 3 pounds of soil fills 8 flower pots.
Using this, we can find our answers to different questions.
Question 1:
We want to know how many pots of soil will fill 1 flower pot.
We know that 3 pounds of soil fills 8 pots. So, to find the amount of soil that fills 1 pot, we can divide 3 by 8:
This is the same as multiplying by a fraction. Namely, is it also 1/8 of 3:
And these are all the choices for the first question.
Question 2:
We want to know how many pots we can fill with 1 pound of soil.
To find this, we can divide 8 pots by 3 to get the unit rate of pots to soil. So:
This is the same as 1/3 of 8:
Which is the same as 1/3 multiplied by 8:
And these are all of the possible choices.
Question 3:
The two remaining ones,
Will go here.
Answer:
an = 5 + 2n
Step-by-step explanation:
Each time it increases by the same amount (2), so this is an arithmetic sequence:
an = a₁ + d (n - 1)
Given a₁ = 7 and d = 2:
an = 7 + 2 (n - 1)
an = 7 + 2n - 2
an = 5 + 2n
Check our answer:
n=1: a₁ = 5 + 2(1) = 7
n=2: a₂ = 5 + 2(2) = 9
n=3: a₃ = 5 + 2(3) = 11
n=4: a₄ = 5 + 2(4) = 13
where is the question you want answered
Answer:
14ab
Step-by-step explanation:
p = 2l + 2w
p = 2(4ab) + 2(3ab)
p = 8ab + 6ab
p = 14ab
