Answer:
3. 4,715 (estimate: 5,000)
4. 3,672 (estimate: 3,300)
5. 18,040 (estimate: 16,000)
6. 9,060 (estimate: 9,000)
Explanation:
It is reasonable if your answer is somewhat close to the estimate.
I think it is 9. But I am not sure if I am correct on it though.
No, .01 is farther from being 1 than .1 is.
5(10)-y=54
50-y=54
-y=54-50
-y=4
y=4/-1
y=-4
hope its help you
