Find the value of x for which a || b.
a
(7x + 2)
b
(8x – 14)

x = 16

Step-by-step explanation:

We know that line a and b are parallel so they each have the same slope therefore, (7x + 2) = (8x - 14).

First we have so isolate a number value and x.

So we subtract 7x from 8x, which looks like:

2 = (x - 14)

Then we have to get that -14 to the other side, so we add and that looks like:

16 = x

Therefore, we have our answer, x = 16.

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
