It's true because since Dallas, Texas is in the United States it is snowing in the United States. Even though all of the United States isn't snowing, Texas is still apart of the United States. Therefore, the following is true.

Answer:

  • large: 55 lb
  • small: 30 lb

Step-by-step explanation:

Let x and y represent the weights of the large and small boxes, respectively. The problem statement gives rise to the system of equations ...

  x + y = 85 . . . . . combined weight of a large and small box

  70x +50y = 5350 . . . . combined weight of 70 large and 50 small boxes

We can subtract 50 times the first equation from the second to find the weight of a large box.

  (70x +50y) -50(x +y) = (5350) -50(85)

  20x = 1100 . . . . simplify

  x = 55 . . . . . . . divide by 20

Using this in the first equation, we can find the weight of a small box.

  55 +y = 85

  y = 30 . . . . . . . subtract 55

A large box weighs 55 pounds; a small box weighs 30 pounds.

Rus_ich [418]
198 x 0.05 = 9.9
198 - 9.9 = 188.1
188.1 x 0.07 = 13.167
188.1 + 13.167 = 201.267

He weighs 201.3 pounds if you round it.
