Respuesta :

Answer:

It said -1 and x 4 we do the opposite and add 1, but divide by 5 because you have to add 4 times p and p to get 5.

24 + 1 = 25

25 / 5 = 5

So P is 5. Double check

5 x 4 = 20 - 1 = 19

19 + 5 = 24

5 is the answer Hope this helps.

Step-by-step explanation:

The purple marbles are 19, the correct option is D.

What is an Equation?

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

The equations are useful in determination of unknown parameters.

The equations are of various types, such as Trigonometric equations, quadratic equations.

The system of equations are used to solve complex problems.

The bag contains 24 blue and purple marbles.

Let the number of purple marbles is p,

Let the number of blue marbles is b,

p = 4b - 1

The equation can be formed as follows:

4b-1 +b = 24

Grouping the variables and constants to solve the equation

5b = 25

Dividing 5 on both sides

b = 5

p = 19

To check,

19+5 = 24

p = 4 * 5 - 1

p = 19
