For the right angle triangles to find the hypotenuse square both the sides that are given and add them together, then you need to square root your answer
If you are finding a different side like triangle 2 use a^2 = c^2 - b^2 where a is the side you are finding, c being the hypotenuse and b being the other side.

Step-by-step explanation:

Step 1: Define Equation

2(6x + 4) - 6 + 2x = 3(4x + 3) + 1

Step 2: Solve for x

Distribute: 12x + 8 - 6 + 2x = 12x + 9 + 1
Combine like terms: 14x + 2 = 12x + 10
Subtract 12x on both sides: 2x + 2 = 10
Subtract 2 on both sides: 2x = 8
Divide 2 on both sides: x = 4

At Shannon's Beading Boutique, 6 out of the 20 beads on clearance are plastic. What percentage of beads on clearance are plastic

yKpoI14uk [10]

Answer:

30%

Step-by-step explanation:

(plastic beads)/(beads on clearance) = 6/20 = 30/100 = 30%

_____

A percentage is a representation of a fraction that has 100 as a denominator. The percent sign (%) is just a shorthand way to write "divided by 100" (/100). The word "percent" means "per hundred", or "divided by 100."

Here, the given fraction (6/20) can be multiplied by 5/5 to make it have a denominator of 100.
