While i was solving the equation for the first try i got it wrong but on the second try i need from my friend he said i must multiply it by 12 then i got the answer. the question is when i solve the equation how do you guys get the 12? i don’t know how you get it but pls. tell me how.

k =3/2

Step-by-step explanation:

8/3k + 2(3/2k+1) = 1/2k +39/4

We want to multiply by 12 because of the fractions.

8/3, 3/2, 1/2, 39/4,  We want to get a common denominator

The common denominator is 12

Multiply each side by 12 to get rid of  ALL the fractions

12(8/3k + 2(3/2k+1)) = 12(1/2k +39/4)

Distribute

12*8/3k + 12*2(3/2k+1) = 12*1/2k +12*39/4

32k +24(3/2k+1)  = 6k +117

Distribute the 24

32k +36k+24=6k+117

Combine like terms

68k +24 = 6k+117

Subtract 6k from each side

68k-6k +24 = 6k-6k+117

62k +24 = 117

Subtract 24 from each side

62k +24-24 = 117-24

62k =93

Divide by 62

k = 93/62

Divide top and bottom by 21

k = 3/2

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
