There are over 2,700 species of snakes .600 species are venomous .what would the fraction of species that are not venomous be as
Radda [10]
So lets just assume first that there are a total of 2700 species of snakes all in all. Out of the 2700 snakes, 600 are known to be venomous. So first of all, let's get the number of the non venomous ones. Subtract 2700 and 600 and you will end up with 2100. So there are a total of 2100 non venomous snakes. So the fraction of the non venomous snakes will be 2100/2700. In its simplified form it is 7/9. In its decimal form (just divide it), you will get an answer of 0.7777.......

Please help with steps??? Question: Find the solution for a system of equations by elimination
Margaret [11]

Answer:

x = -84, y = -58

Step-by-step explanation:

2x - 3y = 6 --- Equation 1

Equation 1×5: <em>10x</em> - 15y = 30 --- Equation 2

5x + 7y = -14 --- Equation 3

Equation 3×2: <em>10x</em> + 14y = -28 --- Equation 4

<u>I will eliminate 10x. </u>

Equation 4-2:

10x - 15y - 10x + 14y = 30-(-28)

-y = 30+28

   = 58

y = -58

Substitute y  =-58 into Equation 1.

2x - 3y = 6

2x - 3(-58) = 6

2x - (-174) = 6

2x + 174 = 6

Find 2x.

2x = 6-174

    = -168

Find x.

x = -168 ÷ 2

x = -84
