Answer:

12 pound

Step-by-step explanation:

Let x be the weight of the package.

For Lone Star Shipping, the cost will be:

2x + 14

For Discount Shipping Company, the cost will be:

1.5x + 20

We hence equate these two expressions equal to each other, since the cost should be same.

2x + 14 = 1.5x + 20 \\2x - 1.5x = 20 -14\\0.5x = 6\\x = 6 \div 0.5\\x = 12

Davey built a bookshelf 36 in. long. Can the shelf hold a set of encyclopedias if there are 24 books and each book averages 5/4
grin007 [14]
Yes, the 36" shelf can hold all 24 books.  As 5/4=1.25" meaning, you take 1.25X24=30".  So 24 books only take up 30 inches of a 36 inch shelf.

He simultaneous equations<br>5x + y = 21<br>x - 3y = 9 <br><br>With working out​
Elza [17]

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

5x + y = 21 → (1)

x - 3y = 9 → (2)

Multiply (1) by 3 and add the result to (2) to eliminate y term

15x + 3y = 63 → (3)

Add (2) and (3) term by term

(x + 15x) + )- 3y + 3y) = (9 + 63)

16x = 72 ( divide both sides by 16 )

x = 4.5

Substitute x = 4.5 into (1) for corresponding value of y

22.5 + y = 21 ( subtract 22.5 from both sides )

y = - 1.5

Solution is (4.5, - 1.5 )

Help PLZZZ
Assoli18 [71]
39 miles. If d=rt and the rate is 16 mph and the time is 3 hours then 16 times 3 gives the distance of 39 miles. I could be wrong but that is what I would have done. I’m not sure if there are answer choices or not
