Given y inversely proportional to x and x = 3 for y = 4, what is x if y = 12?

x = 1

Step-by-step explanation:

Given that;

y inversely proportional to x. This means that as y increases, x decreases and vice versa. Then;

y = k/x

where k is the constant of proportionality

if x = 3 for y = 4 then

4 = k/3, k = 12

y = 12/x. If y = 12 then

12 = 12/x

12x = 12, x = 1

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
