Answer:

Cost of a package of celery = $20

Step-by-step explanation:

Let, x=carrots and y= celery.

So from the given data we get 2 equations

Equation 1]:-

9x+12y=312------------(for 9 package carrot and 12 package celery)

Equation 2]:-

1x+3y=68---------------(for 1 package carrot and 3 package celery)

After solving equation 2 we get,

x=68-3y------------------------(equation 3)

Now substituting equation 3 in equation 1,

9\times(68-3y)+12y=312

612-27y+12y=312

612-15y=312

612-312=15y

300=15y

∴y=\frac{300}{15}

y=20------------------(equation 4)

Therefore cost of a package of celery = $20

Which of the following statements are true about the given rational equation? check all of the boxes that apply. 4 x 6 1 x2 = x
Agata [3.3K]

We can actually see that the statements that are true are:

A. x = 1 is a solution.

C. x = –1 is a solution.

<h3>What is rational equation?</h3>

Rational equation is actually known as an equation that contains at least one fraction. The denominator and numerator are known to be polynomials.

We can see then that:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{x + 10}{ {x}^{3} + 6 {x}^{2}  }

It's clear that: x ≠ 0 and x ≠ -6.

Looking for the LCM of the left hand side, we will have:

\frac{4}{x + 6}  +  \frac{1}{ {x}^{2} }  =  \frac{4 {x}^{2 }  + (x + 6)}{(x + 6) {x}^{2} }

So, we will see that left hand side and right hand side are equal.

4 {x}^{2}  + x + 6 = x + 10

4 {x}^{2}  = 10 - 6

4 {x}^{2}  = 4

{x}^{2}  = 1

x = 1

or

x =  - 1

So, we can see that options A and C are correct.
