Answer:

<u>The small box weights 15 pounds, and the large box weights 45 pounds.</u>

Step-by-step explanation:

1. Let's review all the information given to answer the question correctly:

Weight of small and large box combined = 60 pounds

Truck is transporting 70 large boxes and 55 small boxes

Total weight of the boxes the truck is carrying = 3,975 pounds

2.  How much does each type of box weigh?

Weight of the small box = x

Weight of the large box = 60 - x

For solving the value of x, we use the following equation:

70 * (60 - x) + 55 * x = 3,975

4,200 - 70x + 55x = 3,975

- 15x = 3,975 - 4,200 (Like terms)

- 15x = -225

x = 15 (Dividing by 15 at both sides)

<u>The small box weights 15 pounds, therefore the large box weights 45 pounds (60 - 15).</u>

Nate has 6 3/5 of fabric. He uses 3 1/2 yards of fabric to make a pillow. How much fabric dose he left
NNADVOKAT [17]

Answer:

3 and 1/2  minus 2/3  minus 1/3 =

7/2 minus 2/3 minus 1/3 =

21/6 minus 4/6 minus 2/6 =

17/6 - 2/6 =

15/6 =    5/2 = 2 and 1/2

Optionally, you can think of it this way:

He used 2/3 yards for the pillow and 1/3 yard for the scarf.

So he used 1 yard

3 and 1/2 minus 1 = 2 and 1/2 = 5/2
