8x + (2x - 14)= 7x + 3x -14

10x -14= 10x - 14

These equations are identical, so it would be the  identity property and the answer would either be identity or the fancy 'R'.

Please help, and show work if you can!! :))

Answer:

Step-by-step explanation:

ΔABD ≅ ΔCBD .

So AD = DC

8x - 4 = 3x + 1       {add 4 to both sides}

     8x = 3x + 1 + 4

     8x = 3x + 5 {subtract 3s from both sides}

  8x - 3x= 5

        5x = 5 {divide both sides by 5}

        x = 5/5

x = 1

There are 680 raisins in 8 bags. If each bag has the same number of raisins, how many raisins are in 12 bags?
dmitriy555 [2]

Answer:

  1020 raisins

Step-by-step explanation:

The problem tells you the number of raisins is proportional to the number of bags, so there will be "r" raisins in 12 bags:

  r/12 = 680/8 = raisins/bag

  r = (12/8)(680) = 1020

There will be 1020 raisins in 12 bags.

2. Three bells P, Q and R ring at intervals of 40, 48and 60 minutes respectively. If they ring together at 6.15 a.m. when will t
MAXImum [283]
They will ring again together at 10:15am. Because the common factor for 40, 48 and 60 is 240, which means 240 minutes, that equals to 4 hours. Hence 4 hours after 6.15am is 10.15am.

Hope this helps.

What set of numbers does ^22 fall between
Licemer1 [7]

Answer:

4 and 5

Step-by-step explanation:

If you mean what \sqrt{22} falls into, you would get something in between 4 and 5.

We can solve this by first finding a square root that is higher than that, which is \sqrt{25} and \sqrt{16}.

If we go by that \sqrt{22} falls in between 4² and 5².

Cheers!
