The sum of three numbers is -46. one of the numbers is 24. the other two numbers are equal to each other. what is the value of each of the other two number?

Answer and explanation:

If the sum of the three numbers equal -46 then write an equation for it.

24 + x + x = -46

Since it's three numbers and two of them are equal, you just write the same letter for it (you can choose whichever one you want).

Work out the equation written to get the other two numbers

24 + x + x = -46

24 + 2x = -46  Add the two x's together

-24            -24  Subtract 24 from both sides to cancel it out and leave 2x alone

2x = -72  Divide by 2

So the three numbers would be 24, -36, and -36

24 + (-36) + (-36)

24 + (-72)

-46

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
