3(-6x -5) = 75 pls help me

x = -5

Step-by-step explanation:

3(-6x -5) = 75

Divide each side by 3

3/3(-6x -5) = 75/3

-6x-5 = 25

Add 5 to each side

-6x-5+5 = 25+5

-6x = 30

Divide each side by -6

-6x/-6 = 30/-6

x = -5

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
