Answer:

25 minutes.

Find the perimeter of the square. 5(x+2). x+2(x+8)
erma4kov [3.2K]

Answer:

The length of each of the 4 sides of a square is the same.  Then

5x - 8 = 3x

2x = 8

x = 4

5(4) - 8 = 12

3(4) = 12

The length of each side is

L = 4.

The perimeter is 4 times the length.

P = 4L = 4(4) = 16

Equipment running at 100 per cent capacity sorts 13,000 packages each shift.
kolezko [41]

The machine will sort 11050 packages when it is operating at 85% capacity.

To solve this question, we have to find the rate at which the machine is operating at 85% capacity.

Data;

  • 13,000 at 100%
  • x at 85%

<h3>Rate</h3>

This is used to compare two values with respect to one another mostly under similar conditions.

13,000 = 100\\&#10;x = 85

cross multiply both sides and solve for x

x = \frac{13000*85}{100} \\&#10;x = 11050

The machine will sort 11050 packages when it is operating at 85%
