if y=36 when x=9 find x when y=52
Math help needed here.
Cross-multiply and then solve for x:
36/9 = 52/x
To find the value of x when y is equal to 52, we can use the information given in the first equation: "y = 36 when x = 9."
In this equation, we're given that y is equal to 36 when x is equal to 9. This means that when x = 9, y = 36.
Now, we need to find x when y is equal to 52. We can set up a proportion based on the relationship between x and y.
Let's denote the value of x when y = 52 as x2.
Using the proportion: (x1 / y1) = (x2 / y2), we can substitute the known values:
(9 / 36) = (x2 / 52)
To solve for x2, we can cross-multiply:
9 * 52 = 36 * x2
468 = 36 * x2
To isolate x2, we divide both sides of the equation by 36:
(468 / 36) = x2
Simplifying further:
13 = x2
Therefore, when y is equal to 52, the value of x is 13.
