Answer:
0.0031
Step-by-step explanation:
31/10000=0.0031
you divided by 10000 and it has four zeroes so you should have four numbers after 0
Answer:
1. x = 15
2. x = - 9/7
3. x = 11/3
Step-by-step explanation:
<u>Part</u><u> </u><u>one</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>3</u><u>+</u><u>1</u><u>/</u><u>5</u><u>x</u>
to find x-intercept/zero, substitute y= 0
0 = 3 + 1/5
multiple both sides of the equation by five.
0 = 15 + x
move the variable to the left.
-x=15
change the signs on both of the equations.
x = -15
your solution is x = -15.
<u>Part</u><u> </u><u>two</u><u>,</u><u> </u><u>y</u><u> </u><u>=</u><u> </u><u>-7x</u><u> </u><u>-9</u>
Move variable to the left hand side and change its sign.
7x = -9
Divide both sides of the equation by 7.
x=-9/7
Solution is x = - 9/7
<u>Part</u><u> </u><u>three</u><u>,</u><u> </u><u>y</u><u>=</u><u> </u><u>1</u><u>1</u><u> </u><u>-3x</u>
to find x intercept y and substitute for zero.
0= 11 - 3x
move variable to the left hand side and change its sign.
3x= 11
divide both sides by 3.
x= 11/3
Solution is x = 11/3
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
