If, in 7 years, Susan will be 2 times as old as she was 3 years ago, what is Susan’s present age?
pochemuha

Answer:

13

Step-by-step explanation:

Set Susan's present age as x, her age from 3 years ago as x-3, and her age in three years as 2(x-3)

Since her age in seven years = 2 times as old as she way 3 years ago, set up the equation:

x+7 = 2(x-3)

x+7 = 2x-6

x = 13

Use interval notation to express the set of real numbers x that satisfies the inequality (x+2)(x-5) < 0.
azamat

The interval notation to express the set of real numbers <u>x</u> that satisfies the given inequality is -2<x<5. You also can represent it as (-2,5)

<h3>Inequality</h3>

It is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use following symbols: ≤ (less than or equal to), ≥ (greater than or equal to), < (less than), and > (greater than).

The solutions for inequalities can be given by: a graph in a number line or numbers.

For solving this exercise, it is necessary to find a number solution for the given inequality.

First, you should find the critical points of the inequality.

x+2=0

x = -2

and

x-5=0

x=5

Write, the intervals in between critical points. Therefore, -2<x<5.
