Hi,
8 Pckts each has 500 g weight .Total weight would be 8*500=4000g
and she arranged them into 3 boxes.
assume those three boxes are X,Y,Z first,second,thrid respectively.
X+Y+Z=4000g--------------------1
then according to the statement first box is twice heavy as second one
means X=2Y----------------2
and thrid box is 60g heavier than second box.
Z=Y+60--------------------3
put those values in to eq 1
2Y+Y+Z=4000
3Y+Y+60=4000
4Y=4000-60
4Y=3940
Y=985
second box weight is 985 gram
Step-by-step explanation:
9) given

10)standard form equation: y=mx+c
where m = slope and c = y-intercept
given m = 8, c = 12,
equation of line :

8 to the power -2 = 8^(-2) is equal to 1/64, or 1 / (8^2). Are there any other correct answers? Experiment, please.
Answer:
Well, the x intercept will be -1.5 and the y-intercept will be -3. It will be a negative slope with a slope of -4/2
The answer to your question is 8, because you replace z with 2
