Solve (-5/2) times -5= -55

x= 20

Step-by-step explanation:

-5/2x -5= -55

add 5 to both sides:

-5/2x= -50

multiply 2 to both sides:

-5x= -100

divide -5 to both sides:

x= 20

what is the graph

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
