Answer:
4
Step-by-step explanation:
All the sides of an equilateral triangle are equal, hence the perimeter is expressed as P = 3s
s is one of the side length
Given DE = 5x - 8
P = 3DE
P = 3(5x-8)
36 = 3(5x-8)
36/3 = 5x-8
12 = 5x - 8
5x = 12+9
5x = 20
x = 20/4
x = 4
Hence the value of x is 4
Start by cross multiplying:
41*2 = 5x
Simplify:
82 = 5x
Final answer:
x = 82/5 = 16.4
ANSWER: ⇒ x = 4
Formulate:
2.3 + 3.45 × x = 16.1
Solve the equation:
2.3 + 3.45x = 16.1
Rearrange variables to the left side of the equation:
3.45x = 16.1 - 2.3
Calculate the sum or difference:
3.45x = 13.8
Divide both sides of the equation by the coefficient of variable:
x = ¹³·⁸/₃.₄₅
Multiply both the numerator and denominator with the same integer
x = ¹³⁸⁰/₃₄₅
Cross out the common factor:
x = 4
Answer:
The distance is 4 units.
Step-by-step explanation:
Let the distance between the two points (x₁, y₁) and (x₂, y₂) is
<em>d = √(x₂ - x₁)² + (y₂ - y₁)²</em>
Here, the given points are (2,8) and (6,8), therefore,
x₁ = 2, x₂ = 6,
y₁ = 8, y₂ = 8
d = √(x₂ - x₁)² + (y₂ - y₁)²
d = √(6 - 2)² + (8 - 8)²
d = √(4)² + (0)²
d = √16
d = 4
Thus, The distance is 4 units.
