On the first day of a road trip, Roberto traveled 213 miles from home. On the second day, he drove 149 miles farther. How many miles from home is Roberto at the end of his second day?

Question

*
362 miles
213 miles
149 miles
63 miles

Answer 1

To find out how many miles Roberto is from home at the end of his second day, we need to add the distance he traveled on the first day to the distance he traveled on the second day.

On the first day, Roberto traveled 213 miles. On the second day, he drove 149 miles farther.

So, we can calculate the total distance as follows:

\[ \text{Total distance} = \text{Distance on first day} + \text{Distance on second day} \] \[ \text{Total distance} = 213 \text{ miles} + 149 \text{ miles} \] \[ \text{Total distance} = 362 \text{ miles} \]

Therefore, at the end of his second day, Roberto is 362 miles from home.

Answer 2

For the middle school dance, the student council ordered 18 balloons printed with the school logo. On the night of the party, 4 of the balloons popped. Which problem below represents this scenario using the additive inverse?
*
-18+4
-18 - 4
18 - (-4)
18 + (-4)

Answer 3

The scenario describes starting with 18 balloons and then having 4 of them pop. To express this using the additive inverse, we recognize that popping balloons is equivalent to losing balloons.

Initially, you have 18 balloons. When 4 balloons pop, this represents a loss of 4 balloons. In terms of additive inverse, we represent losing 4 balloons as adding the negative of 4 (which is -4) to the initial number of balloons.

Thus, the expression that represents this scenario is:

\[ 18 + (-4) \]

So, the correct choice is 18 + (-4).
