Mrs. Hines has 40 ballons for a party. She has 12 more balloons than she had for her last party. How many balloons did she have last party? Is there a different equation you can write to show this problem? Explain

28

Step-by-step explanation:

Let the number of balloons that she had last party be represented by x.

Since Mrs.Hines has 40 ballons for a party which was 12 more balloons than she had for her last party. The number of ballons had last party will be formed into an equation as:

x + 12 = 40

Collect like terms

x = 40 - 12

x = 28

She had 28 balloons last year

found it xd it ok yt

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
