UpStudy AI · Accepted Answer

To estimate the sum $$ 4558 + 12,989 + 5113 $$ by rounding each number to the nearest thousand, we will follow these steps:

1. **Round each number:**
   - $$ 4558 $$ rounds to $$ 5000 $$ (since it is closer to $$ 5000 $$ than to $$ 4000 $$).
   - $$ 12,989 $$ rounds to $$ 13,000 $$ (since it is closer to $$ 13,000 $$ than to $$ 12,000 $$).
   - $$ 5113 $$ rounds to $$ 5000 $$ (since it is closer to $$ 5000 $$ than to $$ 6000 $$).

2. **Add the rounded numbers:**
   $$
   5000 + 13000 + 5000
   $$

3. **Calculate the total:**
   $$
   5000 + 13000 = 18000
   $$
   $$
   18000 + 5000 = 23000
   $$

Thus, the estimated sum of $$ 4558 + 12,989 + 5113 $$ is $$ \boxed{23000} $$.
The estimated sum is 23,000.

\( -1 \) \( -2 \) \( -3 \) \( -4 \) \( -5 \) - 6 \( =7 \) Estimate \( 4558+12,989+5113 \) by first rounding each number to the nearest thousand. \( \square \)
