80,000.
To round up to the nearest ten thousand, we would see if the next lower place value has a amount either 5 or higher or 4 or lower.
If it’s five or higher, we round up.
If it’s four or lower, we round down.
We can see that the number in the ten thousands place is 8. The number in the place value after 8 is 2.
2<5 so we round down.
The answer is 80,000.
Hope this helps!
Answer:
x = -7 and x = 3
Step-by-step explanation:
x² + 4x - 21 = 0 factors as follows: (x + 7)(x - 3) = 0.
Then x = -7 and x = 3.
Equation represent situation is 6d = 37.2
<u>Given:</u>
Total distance cover by runners = 37.2 miles
Number of runners = 6
<u>Find:</u>
Equation represent situation
<u>Computation:</u>
Assume;
Each runner cover distance = d miles
So.
Total distance cover by runners = Number of runners × Each runner cover distance
37.2 = 6 × d
6d = 37.2
