Avery gets newsletters by e-mail. he gets one for sports every 5 days,one for model railroads every 10 days tone for music every 8 days. if he got all three today, how many more days will it be until he gets all three newsletters on the same day

If he got them all today the next closest would be 40 days from now. 5*8=40 so 40 is the next closest these two would arrive at the same time, from here we know that 4 and 10 are factors of 40 so he will also get model railroads on this day.

Step-by-step explanation:

-8.3 + 9.2 - 4.4 + 3.7

= -8.3 + 9.2 + (-4.4) + 3.7            {Additive inverse}

= -8.3 + (-4.4) + 9.2 + 3.7            {Commutative Property}

= [ -8.3 + (-4.4] + [ 9.2 + 3.7]       {Associative property}

=  - 12.7 + 12.9

= 0.2
