Answer: If a solution results in zero when subsitituted into the denominator of the equation, the solution is extraneous.

This is because you obtained the solution from a simplified version of the original equation, but you have to check if the solution obtained is a real solution of the original equation

In the case that when you substitute the solution in the original version the denominator becomes zero, this solution must be rejected, because the division by zero is not defined.

A group of friends wants to go to the amusement park. They have no more than $275

Zanzabum

Answer:

10 persons

Step-by-step explanation:

Step one:

given data

We are told that they have a total of $275

also, they want to spend $5 on packing space

and a ticket cost $27 per person.

Step two:

let the number of persons be x

and let the total amount to be spent be y

hence the inequality is

y≤ 5+ 27x

now for y= $275, let us find x

Substitute into the inequality we have

275≤5+27x

275-5≤27x

270≤27x

Divide both sides by 27

x ≤ 270/27

x ≤ 10

Hence the number of persons should not be more than 10

The range of the data

Natali [406]

The range refers to the area where the data points fall from the lowest to highest. Here, the lowest point is 437 and the highest is 1465. So the range is from 437 to 1465
