Let’s solve each problem one by one. We’ll read carefully, do the math step by step, and write the answer in the box.

---

Problem 1: Alex weighs 42 kilograms when she wears her snow suit. She now weighs 72. How much does the teacher weigh?

Wait — this seems odd. It says “Alex weighs 42 kg with her snow suit” and then “she now weighs 72”. But it asks for the teacher’s weight? That doesn’t make sense unless there’s a typo or missing info.

Looking again — maybe it meant to say:
“Alex weighs 42 kg without her snow suit. With her snow suit, she weighs 72 kg. How much does the snow suit weigh?”

That would make more sense. And looking at the picture next to it — it shows a scale with “72” on it, and a kid wearing a snowsuit. So likely, the question is asking:
→ How much does the snow suit weigh?

So:

Weight with snow suit = 72 kg
Weight without snow suit = 42 kg
Snow suit weight = 72 - 42 = 30 kg

But wait — that’s very heavy for a snow suit! Maybe the numbers are switched? Or maybe it’s not about the snow suit?

Actually, let’s re-read the original text:

> Alex weighs 42 kilograms when she wears her snow suit. She now weighs 72. How much does the teacher weigh?

This still doesn’t connect. Unless... perhaps “She now weighs 72” refers to the teacher? But that’s not stated.

Alternatively — maybe it’s a misprint, and it should be:

> Alex weighs 42 kg. When she wears her snow suit, she weighs 72 kg. How much does the snow suit weigh?

That’s logical. Let’s go with that interpretation since otherwise the question makes no sense.

So:

72 (with suit) - 42 (without suit) = 30 kg for the snow suit.

But the question says “How much does the teacher weigh?” — which is confusing.

Wait — look at the image again. The first problem has a star, and below it, a box with “72” and a small figure. Then the question says “How much does the teacher weigh?” — but there’s no mention of a teacher elsewhere.

Perhaps it’s a mistake in the worksheet. Maybe it was supposed to say “How much does the snow suit weigh?”

Given that, and since we have to give an answer, I think the intended question is:

How much does the snow suit weigh?

Answer: 72 - 42 = 30

But let’s hold on — maybe “She now weighs 72” means the teacher? But that’s not said.

Another possibility: Maybe “Alex weighs 42 kg” normally, and “when she wears her snow suit, she weighs 72 kg”, so the suit is 30 kg — and the “teacher” part is a typo.

I think we have to assume that. Otherwise, the problem is unsolvable.

So for Problem 1: 30

Problem 2: Two bags of cement weigh a total of 150 lbs. One bag weighs 96 lbs. How much does the other bag weigh?

Total = 150 lbs
One bag = 96 lbs
Other bag = 150 - 96

Let’s calculate:

150 - 96 = ?

150 - 90 = 60
60 - 6 = 54

So, 54 lbs

---

Problem 3: There are 48 boxes of chocolates in each box. How many will they share by 12 boxes?

Wait — wording is unclear.

It says: “There are 48 boxes of chocolates in each box.” That doesn’t make sense. Probably it means:

“There are 48 chocolates in each box. How many chocolates will they share if they have 12 boxes?”

Yes, that makes sense.

So:

Chocolates per box = 48
Number of boxes = 12
Total chocolates = 48 × 12

Let’s compute:

48 × 10 = 480
48 × 2 = 96
480 + 96 = 576

So, 576 chocolates

---

Problem 4: One box contains 180 tissues. How many tissues are in three boxes?

Simple multiplication:

180 × 3 = ?

100 × 3 = 300
80 × 3 = 240
300 + 240 = 540

Or: 180 × 3 = 540

So, 540 tissues

---

Problem 5: Over's sleds each weigh 95 lb, and he has 13 sleds. How much do all these sleds weigh?

Each sled = 95 lb
Number of sleds = 13
Total weight = 95 × 13

Let’s break it down:

95 × 10 = 950
95 × 3 = 285
950 + 285 = 1235

So, 1235 lb

---

Problem 6: A box has a bottle of lemonade that contains 3 liters. The whole drink is how many liters?

This is tricky. It says “a box has a bottle of lemonade that contains 3 liters.” Then asks “the whole drink is how many liters?”

If there’s only one bottle, and it contains 3 liters, then the whole drink is 3 liters.

Unless “whole drink” means something else — but based on the sentence, it seems straightforward.

Maybe it’s trying to trick us? But no — if the bottle contains 3 liters, and that’s the only thing mentioned, then answer is 3.

So, 3 liters

---

Problem 7: Kitchen countertops can be measured in millimeters. How long is 1.52 m in mm?

We know:

1 meter = 1000 millimeters

So, 1.52 meters = 1.52 × 1000 mm

Multiply:

1.52 × 1000 = 1520

Because moving decimal point 3 places right: 1.52 → 1520

So, 1520 mm

---

Now, let’s list all answers in order:

1. Snow suit weight: 72 - 42 = 30
*(assuming the question meant to ask for snow suit weight)*

2. Other cement bag: 150 - 96 = 54

3. Chocolates in 12 boxes: 48 × 12 = 576

4. Tissues in 3 boxes: 180 × 3 = 540

5. Total sled weight: 95 × 13 = 1235

6. Lemonade volume: 3

7. Convert 1.52 m to mm: 1520

---

Final Answer:
30, 54, 576, 540, 1235, 3, 1520
