An empty book create weighs 30 pounds. what is the greatest number of books weighing 1.5 pounds each that can be packed in the crate if the maximum we must be 60 pounds?

20 books

Step-by-step explanation:you have to do 1.5 times 20 to get 30 punds which is the limit

20 books

Step-by-step explanation:

60-30=30

30/1.5=20

=20

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
