A signle system of linear equations has infinitely many solutions.
Two identical systems of linear equations have infinitely many solutions.
Two systems of linear equations has just one solution.
Two systems of <em>parallel</em> linear equations will has no solutions.
We have two systems of linear equations.
Let's see if they are parallel.
Parallel lines have the same slope.
We'll see if they do by converting to slope-intercept form.
(this will also let us know if they are identical)
1st Eqn.
3x - 9y = 0
Keep y on the left, x and the constant on the right...
-9y = -3x + 0
Divide by the y coefficient.
y = 1/3x + 0
2nd Eqn.
-x + 3y = -3
Keep y on the left, x and the constant on the right...
3y = x - 3
Divide by the y coefficient.
y = 1/3x - 3
As you can see, the two equations have the same slope! (1/3)
Because of this, they are parallel.
And they are not identical because the y-intercepts are different.
There are no solutions to this system of equations.
Multiplying the values given above we obtain a value of 0.01386. In scientific notation, 1.386 x 10^-2. <span>The </span>significant figures<span> of a number are </span>digits<span> that carry meaning contributing to its measurement resolution. From the multiplicand and the multiplier, the least number of significant significant figure would be one. Therefore, we write as
1.0 x 10^-2</span>
1/6 - 6,12,18,24 (we counted by 6's, 2 times to get 12)
1/4 - 4,8,12,16 (we counted by 4's, 3 times to get 12)
12 is the LCD (Lowest Common Denominator) of the 2 fractions
*Now that we have the denominator, we need to find the numerator
1/12 - 1x2 (why 2? well because we had to count by 6's, 2 times to get 12)
1/4 - 1x3 (why 3? well because we had to count my 4's, 3 times to get 12)
2/12 and 3/12 is the answer
I hope you get it!!
Answer:
172.5 bushels per acre
Step-by-step explanation:
15%=0.15
0.15*150=22.5
150+22.5=172.5
