D. 549 = 6:3

no i do not : ( what is it?

let "a number" = "x"

note that increased = +

x + 3.5 = -4.3

solve for x. note the equal sign. what you do to one side, you do to the other. subtract 3.5 from both sides

x + 3.5 (-3.5) = -4.3 (-3.5)

x = -4.3 - 3.5

x = -7.8

-7.8 is your answer for x

~rise above the ordinary

okay so, you must add the total of monday amd tuesday

4.32+6.86=11.18

then you subtract the totals from this week and last week

11.18-7.89=3.29

3.29 rounds to 3.30 aka 3.3

the answer is a -1.5
