Hank likes to bake cake, and so he needs 3 eggs per cake. Write an expression to show how many eggs he will need if he bakes x cakes. Then, write an equation to determine how many eggs he will need to bake 11 cakes. Explain how you came up with the expression or equation, or how to use them to answer the problem

3 eggs per cake = 33 eggs for 11 cakes

Step-by-step explanation:

if you multiply by 3 by 11 you get 33 so therefor for each one cake you need three eggs and for 11 cakes you will need 33 eggs  

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
