A machine produces 158 items in 12 minutes.
At the same rate, how many items will it produce in 8 hours?
**Weegy:** There are 5 lots of 12 minutes in an hour.
5 x 158 = 790 items per hour.
790 x 8 = 6320 items in 8 hours. **User:** Simplify
20 ÷ (32 + 4 - 23)
**Weegy:** 23+23= 46 **User:** Find the length of the diagonal of a rectangle with 5 inch width and 7 inch length.

One number is 8 more than another number. If the sum of the smaller number and twice the larger number is 46, find the two numbers.
User: solve for x 3x - (1/2) = 2x + (7/4)
**Weegy:** x = 27/4 **User:** solve for x 2x + 3(4 - x) = 3x + 2
**Weegy:** Here's the solution:3x - 5 **User:** solvel for x x2 - 3x - 4 = 0
**Weegy:** x2 - 3x - 7 = 0 x = 1/2 (3-sqrt(37)) x = 1/2 (3+sqrt(37)) **User:** solve for x: x2 - 3x - 4 = 0
**Weegy:** Here's the solution:3x - 5 **User:** add: 9x4 -3x2 and 4x2+5
**User:** add: 9x4 -3x2 **User:** multiply (x3 - 6x2 + 3x - 1) ÷ (x - 5) **User:** factpofactor 3x2 - 4x - 4
**Weegy:** (3x-1)(-2x-1) **User:** factor 3x2 - 4x - 4
**Weegy:** It is: x = -7. [smile] **User:** Maria bought 56 stamps at the post office. The stamps were 37 cents and 20 cents. If she paid $18 for the stamps, how many of each denomination did she buy?

3x - (1/2) = 2x + (7/4)

3x - 2x = (7/4) + (1/2)

x = 9/4 = 2 1/4

3x - 2x = (7/4) + (1/2)

x = 9/4 = 2 1/4

2x + 3(4 - x) = 3x + 2

2x + 12 - 3x = 3x + 2

-x + 12 = 3x + 2

-x - 3x = 2 - 12

-4x = -10

x = -10/-4 = 2.5

2x + 12 - 3x = 3x + 2

-x + 12 = 3x + 2

-x - 3x = 2 - 12

-4x = -10

x = -10/-4 = 2.5

x^2 - 3x - 4 = 0

(x - 4)(x + 1) = 0

x = 4 or x = -1

(x - 4)(x + 1) = 0

x = 4 or x = -1

(9x^4 - 3x^2) + (4x^2 + 5)

= 9x^4 - 3x^2 + 4x^2 + 5

= 9x^4 + x^2 + 5

= 9x^4 - 3x^2 + 4x^2 + 5

= 9x^4 + x^2 + 5
