Eight times a number equals 24 more than two times the number. what is the number

4

Step-by-step explanation:

I'll use  n  to represent the unknown number.

8 n  = 24 + 2 n

→ times means multiplication (8 times a number  n  means  8 ⋅

n  or  8 n  ,the same thing goes for 2 times the number), 24 more than  2  n  indicates that  2 n  is being increased by 24 ( 24 + 2 n )

6 n = 24 n = 4

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

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
