Answer:
just circulate little numbers of the answers bellow -_-
Step-by-step explanation:
cause u said "does anyone know how to do the first question?"
128.59943 rounds to about 128.599 because the next decimal is a 4 and your round down below 5.
Answer:
no it doesn't because if the number in the first column increase then the number in the second column shouldn't be decreasing also the constant between 85 and 5 was 17 but the constant between 10 and 79 wasn't the same
To do this let's put 129 where X is, like this: -12(129)+14(129)-6(129)
Now we multiply -12 by 129, which is equal to -1548.
Now we multiply 14 by 129, which is equal to 1806.
Now we multiply -6 by 129, which is equal to -774.
Now, let's put these numbers into an equation, like this: -1548+1806-(-774).
The answer to this equation is 1032.
I hope this helps.
Part A:
1) 16
