Suppose PR = 54, solve for QR<br> 4x-1<br> 3x-1<br> P<br> R
Svet_ta [14]

Answer:

QR = 23

Step-by-step explanation:

P, A, and R are collinear.

PR = 54

PQ = 4x - 1

QR = 3x - 1

To solve for the numerical length of PR, let's generate an equation to find the value of x.

According to the segment addition postulate:

PQ + QR = PR

(4x - 1) + (3x - 1) = 54 (substitution)

Solve for x

4x - 1 + 3x - 1 = 54

Combine like terms

4x + 3x - 1 - 1 = 54

7x - 2 = 54

Add 2 to both sides

7x - 2 + 2 = 54 + 2

7x = 56

Divide both sides by 7

\frac{7x}{7} = \frac{56}{7}

x = 8

QR = 3x - 1

Plug in the value of x into the equation

QR = 3(8) - 1 = 24 - 1

QR = 23

Lace edging is sold by the foot for $0.80 or by the foot for $1.99. Which is more expensive
vampirchik [111]

Answer:

$1.99 is more expensive.

Step-by-step explanation:

Given:

One type of lace edging cost $0.80 per foot

Another type of lace edging cost $1`.99 per foot.

We need to find which is more expensive.

In $0.88 where one's place is 0.

In $1.99 where one's place is 1.

By comparing the one's place obviously $1.99 more expensive.

Hope you will understand the concept.

Thank you.
