Write the interval (5,100] as an inequality and using set notation

drek231 [11]

Answer: { x | 5 < x ≤ 100 } OR { x ∈ ℝ | 5 < x ≤ 100 }

Step-by-step explanation:

{ x | 5 < x ≤ 100 }

This means:

"The set of all x's, such that x is greater than 5 and less than or equal to 100"

Another acceptable way to write this is

{ x ∈ ℝ | 5 < x ≤ 100 }

"x ∈ ℝ" simply means x is an element of all real numbers

Reina's family is taking a road trip. Their car can travel no more than 304 miles without needing to refill the gas tank. They h

Natalka [10]

Solving the inequality, it is found that the correct interpretation of the solution is:

Reina's family can drive 83 more miles before they need to refill the gas tank.

The amount x of miles they can still travel is modeled by the following inequality:

$221 + x \leq 304$

To solve it, we treat it similarly to an equality, hence:

$x \leq 304 - 221$

$x \leq 83$

Hence:

Reina's family can drive 83 more miles before they need to refill the gas tank.
