-12=-8z+12 please need help​

z=3

Step-by-step explanation:

-12=-8z+12

-12-12=-8z

-24=-8z

-24/-8=z

z=24/8

3=z

z=3

Answer and Step-by-step explanation:

To solve for z, we have to get everything away from z.

First, subtract 12 from both sides of the equation.

-24 = 8z

Now, divide each side by 8.

-3 = z

z is equal to -3 (negative three).

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
