Create a proportion: 8000/4 = 7000/x

8000x = 28000

then divide

8000x/8000 = 28000/8000

that equals x = 3.5 tons

---------------------------------------------------------OR---------------------------------------------------

Create a proportion 8000/4 = 7000/x

then simplify to 2000/1 = 7000/x

7000 = 2000x

then divide

7000/2000 = 2000x/2000

3.5 tons = x

Answer:

The answer to your question is:

61.- 25

62.- 26

Step-by-step explanation:

61.-

     2(5x + 5) + 2(2x) = 360

     10x + 10 + 4x = 360

     14x = 360 - 10

     14x = 350

     x = 350/14

     x = 25

62.-

     2(4x - 4) + 2(3x + 2) = 360

     8x - 8 + 6x + 4 = 360

     14x - 4 = 360

     14x = 360 + 4

     14x = 364

     x = 364 / 14

    x = 26

If I lost 4% of 100 pencils an 6% of 200 pens how many pencils do I have left and how many pens do I have left?
DedPeter [7]
To find 4% you multiply 100 by .04
100•.04=4
Then subtract
100-4=96 *you have 96 pencils left*

To find 6% of 200, multiply 200 by .06
200•.06=12
Then subtract
200-12=188 *you have 188 pens left*
