Whta is 80 - (-9) = explain pls

80 - (-9) = 89.

Explanation:

In math, two negatives next to each other will become a positive. Since a negative number is being subtracted, The negatives will cancel.

So this:

80 - (-9)

Is functionally the same as this:

80 + 9

Therefore, the answer is 89.

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
