Answer is 800
because if you do
1440=0.8t+t
1440=1.8t
800=t
so the first day is 800 tons and the second day is 640 tons

The answer you are looking for is B. If you use the FOIL method (first,outer,inner,last) of multiplication, you will find that (x+5) times (x-5) is actually x^2+25. Hope this helps! Comment if you have questions!!! :)

Answer:

D

Step-by-step explanation:

$\frac{1}{2} = \frac{7}{14} \\$

$\frac{1}{7} = \frac{2}{14}$

$\frac{7}{14} + \frac{2}{14} = \frac{9}{14}$

5+2=7

$7 + \frac{9}{14} = 7 \frac{9}{14}$
