The value of y is directly proportional to the value of x. if y=65 when x=5, what is the value of y when x=12?

Y=65
X=5
X=12
Y=?

65—->5
?——>12

Cross multiply

Y= (65x12) / 5
Y= 780 / 5
Y= 156

To check add the Y value in and remove an X value

65——> ?
156 ——> 12

Cross multiply

X= (12x65) / 156
X= 780 / 156
X= 5

You got the right answer. Hope this helped.

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
