Answer: 1/12 || 2x-1/2=2x-1/12
Let the cost of one sheep and one cow be x and y respectively.
Therefore,
5x+5y=129
10x+17y =177
Solving the two equations,
Multiply the first equation by 2 and subtract the second from the results;
10x+10y = 258
10x+17y = 177
0x-7y = 81 => y= $-11.57 (cannot be a negative value). The details of the question need to be checked.
Now,
5x+5y = 129 => 5x-57.86 =129=>5x = 186.86 => x= $37.37
Answer:
The first number should be a number between 1 and 10 (see explanation)
Step-by-step explanation:
For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.
36.5 is not between 1 and 10, alternatively, you can rearrange it:
3.65 x 10^7 <----This would be the correct scientific notation
The answer would be A. Oval
