Directions: Find the value of x.
104
(9x - 25)

x = 7

Step-by-step explanation:

Since the two sides (9x - 25) of the triangle are congruent to each other, we can add them together

(9x - 25) + (9x - 25)

18x - 50

A triangle is 180 degrees when adding all three sides

So if 2 sides together equal 18x - 50 and the last side equals 104, then they should equal 180 total

18x - 50 + 104 = 180

Combine like terms

18x + 54 = 180

Subtract both sides by 54 to isolate the variable

18x + 54 - 54 = 180 - 54

18x = 126

Divide both sides by 18 to isolate the variable

18x ÷ 18 = 126 ÷ 18

x = 7

Check your work by plugging in the x value for the expression and adding all three sides to equal 180 degrees

9(7) - 25 + 9(7) - 25 + 104 = 180

Pemdas says to multiply first

63 - 25 + 63 - 25 + 104 = 180

38 + 38 + 104 = 180

76 + 104 = 180

180 = 180

The work is correct

yes

yes yes yes

answer: answer is c!

ok i got to organize the

3/15 and 12/55

3*

aha

3*4 equals 12 but not

a: no

b:

8/24 12/35

no

gautie

it's c

5/18 = 25/90

5*5=25

18*5 = 90

hope that you!

one more happy customer!
