Triangle def is equilateral. If the perimeter of def is 36, the length of de is 5x-8, then what is the value of x

Mathematics

My name is Ann [436]3 years ago
3 0

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

Suppose the current cost of gasoline is
Elodia [21]

Answer:

The current price index number is $604.2.

Step-by-step explanation:

The index value is the ratio between the current value and the reference value, multiplied by 100.

In this problem, we have that:

Current value = $3.48

Reference value: $0.576

Index price = (3.48/0.576)*100 = $604.2.

The current price index number is $604.2.

Use the picture below to solve for the missing information, given PQ = 2x + 8, QR = x + 11, and PR = 5x - 3.
dmitriy555 [2]

Given that Q is a point between P and R, the numerical values of x, segment PQ, QR and PR are 11, 30, 22 and 52 respectively.

<h3>What are the numerical values of x, segment PQ, QR and PR?</h3>

Given the data in the question;

  • Q is a point between P and R
  • Segment PR = 5x - 3
  • Segment PQ = 2x + 8
  • Segment QR = x + 11
  • Numerical value of x, segment PQ, QR and PR = ?

Since Q is a point between P and R.

PR = PQ + QR

Plug in the given values and solve for x.

5x - 3 = ( 2x + 8 ) + ( x + 11 )

5x - 3 = 2x + 8 + x + 11

5x - 3 = 3x + 19

5x - 3x = 19 + 3

2x = 22

x = 22/2

x = 11

Numerical value of segment PQ when x = 11 will be;

PQ = 2x + 8 = 2(11) + 8 = 30

Numerical value of segment QR when x = 11 will be;

QR = x + 11 = (11) + 11 = 22

Numerical value of segment PR when x = 11 will be;

PR = 5x - 3 = 5(11) - 3 = 52

Given that Q is a point between P and R, the numerical values of x, segment PQ, QR and PR are 11, 30, 22 and 52 respectively.
