Identify the property used in Step 1. Step 1 4 + 6x + 11 + 12x - 11 = 4 + 6x + 11 + (12x - 11) Step 2 = 4 + 6x + 11 + (-11 + 12x) Step 3 = 4 + 6x + [11 + (-11)] + 12x Step 4 = 4 + 6x + 0 + 12x Step 5 = 4 + 6x + 12x Step 6 = 4 + (6 + 12)x Step 7 = 4 + 18x Step 8 = 18x + 4

sorry It wont let me click off

Step-by-step explanation:

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
