Write the equation 8y = 1/12x – 0.8 in standard form. identify a, b, and c.

a. 480x + 5y = –48 where a = 480, b = 5, and c = -48

b. 480x – 1y = –48 where a = 480, b = –5, and c = -48

c. 5x – 480y = 48 where a = 5, b = –480, and c = 48

d. 1x + 96y = 9.6 where a = 1, b = –96, and c = 0.8

Naswer C:

Step-by-step explanation:

Let's first write all the coefficients in fraction form, noticing that 0.8 is the same as , and then group the term in x and the term in y on one side of the equal sign, moving the pure numerical coefficient to the other side:

Now find the LCD for the existing denominators (5 and 12). This is: LCD = 60

Use the LCD we just found, to multiply both sides of the equation, so as to get rid of all denominators in the equation:

notice that our equality matches answer C provided.

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
