<span>Carl has 3 bags in total. One backpack weighs 4 kg and the rest two checking bags have the equal weight. The total weight of 3 bags is given to be 35 kg.
Let the weight of each checking bag is w kg. So we can write:
2 x (Weight of a checking bag) + Weight of Backpack = 35
Using the values, we get:
2w+ 4 = 35
Using this equation we can find the weight of each checking bag, as shown below.
2w = 31
w = 31/2
w = 15.5
Thus, the weight of each checking bag is 15.5 kg

All 32 glue sticks cost 44.80 dollars and all the crayon boxes cost 18.88 dollars. She spent 63.68 dollars. She has 16.32 dollars left.
The answer is negative 80 or like this -80
(-1,-4) this is saying that when x=-1, y=-4. Plugging it into the line equation y=4x gives
Which is correct.
We know that
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m
I apply a rule of three to know the time
if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec
to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes
to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours
1.1576518= 1 hour 9 minutes 27.55 sec
the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)
