e, If you do something to one side of the equation, you must do it to the other

d, To undo addition, you can use multiplication

Step-by-step explanation:

a, To remove a whole number next to the variable, multiply both sides by that number

a) t'(-3, 6) and v'(0, 3)  

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
