There are 96 marbles in a box. there are 5 times as many blue marbles as red marbles. how many red marbles are there?

16

Step-by-step explanation:

96 marbles = Box

Let's call blue marbles " 5 x " and red marbles " x "

So now an equation is setup ⇒

→ 5 x + x = 96

( Simplify )

→ 6 x = 96

( Divide by 6 from both sides to isolate x )

→ x = 16

red marbles " x " so x = 16

You would use the following equation:

96 = 5x + x

There is a total of 96 marbles. The right side of the equation represents how many blue marbles are in the box. X is red marbles in the box, since we know that red marbles is 5 times x

Add the common variables:

96 = 5x + x

96 = 6x

To solve for red marbles isolate x. To do this divide 6 to both sides. Division is the opposite of multiplication and will cancel 6 from the right side and bring it to the left

96 ÷ 6 = 6x ÷ 6

16 = x

You have 16 marbles in the box
