There are ____orange balls and _____ green balls in the box.

Sagot :

Answer:

15 orange balls and 39 green balls

Step-by-step explanation:

Orange balls = x

Green balls = 2x + 9

2x + 9 + x = 54

3x + 9 = 54

3x = 45

x = 15

There are 15 orange balls and 39 green balls in the box.

Given that, the total number of balls=54 balls.

The number of green balls is nine more than two times the number of orange balls.

What is an equation?

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of orange balls be x. Then, green balls will be 2x+9.

Now, x+2x+9=54

⇒3x+9=54

⇒3x=45

⇒x=15

Therefore, there are 15 orange balls and 39 green balls in the box.
