MM. 2 Write variable expressions: word problems E2M 4)) [xA, Nathan lives 8 blocks from school. He just left school and walked \( b \) blocks toward home. Choose the expression that shows the number of blocks remaining. Submit \( b-8 \) \( 8+b \)

To solve the problem, we need to express the number of blocks Nathan has remaining to walk home after he has already walked \( b \) blocks toward home. 1. **Known Conditions:** - Nathan lives 8 blocks from school. - He has walked \( b \) blocks toward home. 2. **Understanding the Problem:** - Initially, Nathan has 8 blocks to walk home. - After walking \( b \) blocks, the remaining distance to home can be calculated by subtracting the blocks he has already walked from the total distance. 3. **Formulating the Expression:** - The expression for the number of blocks remaining to walk home is: \[ \text{Remaining blocks} = 8 - b \] 4. **Choosing the Correct Expression:** - The options provided were \( b - 8 \) and \( 8 + b \). - Neither of these options correctly represents the remaining blocks. The correct expression is \( 8 - b \). Thus, the correct expression for the number of blocks remaining is \( 8 - b \).
