(8 + 2c) + (-4 + 5m) + (7 + 3n)
group the like terms to simplify the equation

11+2c+5m+3n

Step-by-step explanation:

8-4+7=11

you cant add 2c,5m,and 3n so you just leave them as 2c+5m+3n

then you add 11 to it and get 11+2c+5m+3n

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

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)
