An equilateral triangle is a triangle in which all three sides have the same length![.](https://tex.z-dn.net/?f=.)
⭆ 14 = 3x - 4
⭆ 3x = 14 + 4
⭆ 3x = 18
⭆ x = 18/3
⭆ x = 6
In equilateral triangle, all three internal angles are also same and each are of 60°.
⭆ 5y - 5 = 60
⭆ 5y = 60 + 5
⭆ 5y = 65
⭆ y = 65/5
⭆ y = 13

<h3>Hope It Helps!</h3>
9/2 = 81/a....9 kids meals to 2 adult meals = 81 kids meals to a adult meals
cross multiply
9a = 2(81)
9a = 162
a = 162/9
a = 18...so there were 18 adult meals
ratio is : 81/18
If the perimeter is 30
and the length is twice the width
c=length
w=width
2c=w
a pool table has 4 sides, the two adjacent sides will be equal so we only need to account for 1 of the widths and 1 of the lengths
meaning we only need to use half of the perimeter, or 15
if the length is twice as long as the width
the length would be 10
the width would be 5
there are two widths and 2 heights so the perimeter would correctly add up to 30 feet, proving you have the right answer
