At the middle avenue school 1/30 of the students are on track team the track coach offered to buy pizza or subs for everyone on

Aleksandr-060686 [28]

Answer:

$Students = \frac{1}{50}$

Step-by-step explanation:

Given

$Track = \frac{1}{30}$

$Pizza = \frac{3}{5}$

Required

The fraction of students in the school that ate Pizza

To do this, we simply multiply the fraction of track students and those among them that ordered pizza.

So, we have:

$Students = Pizza * Track$

$Students = \frac{3}{5} * \frac{1}{30}$

$Students = \frac{1}{5} * \frac{1}{10}$

$Students = \frac{1}{50}$

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.

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

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

$4 {x}^{2} = 4$

${x}^{2} = 1$

$x = 1$

$x = - 1$

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

Given 7x + 2 > 58, which number is not in the solution set?

Hoochie [10]

Answer:

option 1

Step-by-step explanation:

7x + 2 > 58 ( subtract 2 from both sides )

7x > 56 ( divide both sides by 7 )

x > 8

So only values greater than 8 are in the solution set

6 is not greater than 8, then is not in the solution set
