864? not quite sure what you're asking here
-7.1-3.2 extract the negative sign and then add the negative numbers -(7.1+3.2) your answer would be -10.3
$3, $1, $5, $2, $3, $9, $1 = $24 - $1 = $23 - $1 = $22.
$22 is the estimation of the bill when all of the amounts are rounded to the nearest dollar. The estimation is greater than the total bill which is 23 cents less than the estimation. The total on the register is reasonable and accurate.
I’m not sure what they are asking for. One way is -6(2x -4 + 3y)
That’s really the only way to factor it
