Please give me the correct answer.Only answer if you're very good at math.​
GaryK [48]

Answer:

-9 = 0.45m

Step-by-step explanation:

0.45m - 9 = 0.9m

  • ^ Subtract 0.45m from BOTH sides. so 0.9m - 0.45m... etc
  • Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
  • That will equal to:

-9 = 0.45m     <-- ANSWER

Find the sum.<br> 48 + 45 + 42+...+(-81) + (-84)
Agata [3.3K]

Answer:

look below

Step-by-step explanation:

i dont know what that +... thing is

but when youre adding the negatives youre really just adding that number so this is just

48+45+42+81+84

45+42 is 87

now we have

48 + 87 + 81 + 84

87 + 81 is 168

48 + 84 is 132

now we have

168 + 132 and that is exactly 300

again dont know what the ... is so cant help you there
