40 I'm not quite sure but I think that might be the ANWSER!
Answer: $1.5
Step-by-step explanation:
$3.00 divided by 2 pounds is $1.5
$4.50 divided by 3 pounds is $1.5
and $6.00 divided by 4 pounds $1.5
terms: -5x, 4, -x, -1
like terms: 4 and -1, -5x and -x
coefficients: -5 and -1
constants: 4 and 1
(depending on your teacher, the - could not be considered part of the coeficient, meaning the coefficents would be -5 and 1, as well as just x, not -x)
