What are the solutions to the following math problems: 1. Write 49210 in expanded form. 3. What number must be subtracted from 9000 to get 4608? 4. One step of a man is 1m. How far will he move in 418

here are the solutions to your homework questions:

1. Write 49210 in expanded form.

Step 1: Identify the place value of each digit in 49210.

• The digit 4 is in the ten thousands place, so its value is $4 \times 10,000$.
• The digit 9 is in the thousands place, so its value is $9 \times 1,000$.
• The digit 2 is in the hundreds place, so its value is $2 \times 100$.
• The digit 1 is in the tens place, so its value is $1 \times 10$.
• The digit 0 is in the ones place, so its value is $0 \times 1$.

Step 2: Write the number as the sum of these place values.

$$49210 = 4 \times 10000 + 9 \times 1000 + 2 \times 100 + 1 \times 10 + 0 \times 1$$

4 \times 10000 + 9 \times 1000 + 2 \times 100 + 1 \times 10 + 0 \times 1

2. Write the total value of x in cm.
This question is incomplete as the value of 'x' is not provided in the image. Please provide the value of 'x' for me to solve this.

3. What number must be subtracted from 9000 to get 4608?

Step 1: Let the unknown number be $N$.
The problem can be expressed as an equation:

$$9000 - N = 4608$$

Step 2: To find $N$, subtract 4608 from 9000.

$$N = 9000 - 4608$$

Step 3: Perform the subtraction.

$$N = 4392$$

The number that must be subtracted is 4392.
4392

4. One step of a man is 1m. How far will he move in 418 steps?

Step 1: Identify the distance covered in one step and the total number of steps.
Distance per step $= 1 \text{ m}$
Number of steps $= 418$

Step 2: Multiply the distance per step by the number of steps to find the total distance.

$$\text{Total distance} = \text{Distance per step} \times \text{Number of steps}$$ $$\text{Total distance} = 1 \text{ m} \times 418$$ $$\text{Total distance} = 418 \text{ m}$$

He will move 418 m.
418 m
