1. Lily wants to buy 4 pounds of cereal for her camping trip. The boxes are each 18 ounces. According to the number line, how many boxes will she need to buy to have at least 4 pounds? 18 36 72 +++ 26 32 48 80 1: 2 boxes
2: 5 boxes
3: 3 boxes
4: 4 boxes ​

4 boxes.

Step-by-step explanation:

We know that each box has 18 ounces of cereal.

We know that:

1 lb = 16 oz

Then:

1 = (1lb/16oz)

Then we can write:

18 oz = 18oz*(1lb/16oz) = (18/16) lb

This means that each box has (18/16) pounds of cereal.

Now, how many boxes we need to buy if we want to have at least 4 pounds of cereal?

If we buy N boxes, we will have N*(18/16) lb boxes of cereal.

Let's find N such that:

N*(18/16) lb = 4lb

N = 4*(16/18) = 3.56

But you can not have a 0.56 of a box, so we should round our number up to the next whole number, then we get:

N = 4.

She should buy 4 boxes.

4 boxes

Step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
