Answer:
smaller number = 623
middle number = 625
larger number = 627
Step-by-step explanation:
Variable: X = smallest number
If these numbers are consecutive and odd, then the numbers would be:
x, x+2, x+4
x + (x + 2) + (x + 4)= 1875
3x + 6 = 1875
3x = 1869
x = 623
x + 2 = 625
x + 4 = 627
Check:
623 + 625 + 627 = 1875

Answer:
9 tons
Step-by-step explanation:
So first we have to figure out the area of the smaller wall. We know it is 10 feet high and 20 feet long, so we multiply the length and width together to get 200 square feet, and that equals 1 ton. Now if we take the 1800 square foot wall and divide it by the smaller wall, we get 9. This is because the larger wall is 9 times the size of the smaller wall. So if the smaller wall needs 1 ton, and the larger would need 9 times the amount, we would need 9 tons.
