Answer:

B. 61

Step-by-step explanation:

Given:

∆PQR ≅ ∆PQS

PQ = 2x + 41

QS = 7x - 24

QR = 3x + 16

Required:

Numerical value of PQ

SOLUTION:

First, create an equation to find the value of x as follows:

Since both triangles are congruent, therefore:

QS = QR

7x - 24 = 3x + 16 (Substitution)

Collect like terms

7x - 3x = 24 + 16

4x = 40

Divide both sides by 4

4x/4 = 40/4

x = 10

Find PQ by plugging x = 10 into PQ = 2x + 41

PQ = 2(10) + 41

PQ = 20 + 41

PQ = 61

8x-3y+24=48 in slope intercept form

disa [49]

Hello!

Slope-intercept form is written as y = mx + b. In this form, m is the slope and b is the y-intercept. Remember to use SADMEP when solving algebraic equation. This main goal is to get y by its self.

(SADMEP = subtraction, addition, division, multiplication, exponents, parentheses)

8x - 3y + 24 = 48 (subtract 24 from both sides)

8x - 3y = 24 (subtract 8x from both sides)

-3y = -8x + 24 (divide both sides by 3)

y = 8/3x + -8

Therefore, the final answer is y = 8/3x + -8.
