Consider the equation 3p – 7 + p = 13. what is the resulting equation after the first step in the solution? p – 7 = 13 – 3p 2p – 7 = 13 3p – 7 = 13 – p 4p – 7 = 13

D. 4p – 7 = 13

Step-by-step explanation: All p terms are already on the left, so your first move is to group them.  Taking 3p and adding p, we get 4p - 7 = 13.  So the correct answer is the last one.

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
