Y and x have a proportional relationship, and y = 25 when x = 60. What is the value of x when y = 30?

1 answer:

3 0

The equation governiong this relationship is y = kx. Since y = 25 when x = 60,
25 = 60k, and k=(5/12). Thus, the equation is y = (5/12)x.

If y = 30, then 30 = (5/12)x. Mult. both sides by 12/5 to obtain the value of x:

(12/5)(30) = 360/5 = 72

Answer: 10 and 11, also -11 and -10

Sqrt 100 is well known to be 10

Sqrt 121 is 11

Step-by-step explanation:

Positive Sqrt is monotone increasing

So Sqrt 105 is between sqrt 100 and sqrt 121

Second answer

Sqrt 100 is less well known to also be -10

Negative sqrt is monotone decreasing

Sqrt 121 is also -11

Sqrt 105 is also between -121 and -100
