Travis and his three friends went to dinner to celebrate graduation. the guys decided to divide the bill evenly. each person paid $15.
which equation can be used to find the total amount of the bill?
x/3=15
15x=3
x/4=15
15x=4

The answer is $60.00

Step-by-step explanation:You have to multiply 15 by 4 which is equal to 60

The correct answer is $ 60. That is 3rd equation x/4=15.

Step-by-step explanation :                                                                                                                  

According to question, total person are four and each person is paying $15.

That means we have to multiply the amount paying by the each person to the number of persons.

Accordingly, 15 * 4 = 60

So 60 is the answer

Now, according to equation 1.    

i.e., x/3=15

so 60/2=20  

and 15 is not = 20

so this equation is not correct.

Now, according to 2nd equation

i.e., 15x=4

so 15 * 60 =900

and 900 is not equal to 15

according to 3rd one

i.e., x/4=15

so 60/4=15

and 15=15

so, this equation is used  to find correct answer.

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
