The boxes weigh 12 pounds and 20 pounds respectfully. We found this by setting up and solving an equation based on the problem's parameters.
Let's assume the lighter box weighs 'x' pounds, this makes the heavier box weigh 'x+8' pounds. According to the problem, the total weight of both boxes that the mail truck picks up from the post office is 32 pounds. So, we can set up the following equation: x + (x+8) = 32. Solving this equation we get 2x = 24, which means x = 12. So, one box weighs 12 pounds and the other box, which is 8 pounds heavier, weighs 20 pounds.

Answer: Hello mate!
We have the equation 13 + 52 and we want to write this as the product of their GCF and another sum.
The GCF between 52 and 13 can be obtained in the next form:
52/13 = 4, then 52 = 13*4
then 13 is a factor of 52, and 13 is the GCF between 13 and 52.
our equation can be written as:
13 + 52 = 13 + 13*4 = 13*(1 + 4)
there you have the equation written as the product between the GCF between 13 and 52 and another sum.
1/4 - [-3/8]
Negative times negative become positive
Now to add fractions we make the denominator same
4 and 8 are in the denominator
Least common denominator of 4 and 8 is 8
To make denominators same , we multiply the numerator and denominator of first fraction by 2.
The denominators are same so we combine the numerators
