N a small storage bin, there is a collection of Legos. There are 15 red bricks, 10 yellow bricks, 8 blue bricks and 7 green bricks. One Lego brick is randomly selected, what is the probability that it is a yellow brick? Round to two decimal places if needed

20 blue, 10 red, 40 yellow. There are no clues to how many black.

Step-by-step explanation:

Your answer is x = 1

Step-by-step explanation:

First start by distributing 5 to everything in the parenthesis.

5 * 2x = 10x

5 * -8 = -40

What you're left with is 10x - 40 + 15 = -15

Next subtract 15 from both sides.

10x - 40 + 15 - 15

The 15's will cancel each other out on the left side.

-15 - 15 = -30

What you're left with is 10x - 40 = -30

Next add 40 to both sides.

10x - 40 + 40

The 40's will cancel each other out on the left side

-30 + 40 = 10

What you're left with is 10x = 10

Divide both sides by 10 to get x by itself.

10x / 10 = x

10 / 10 = 1

What you're left with is x = 1
