Question

Percy is plotting points on a graph. The ratio of y-value to x-value is 2 to 3 for each point. What will be the x-value of a point with a y-value of 18?

Answer 1

Answer: Value of x = 27

Explanation:

Percy is plotting a coordinate on the graph.

Now the ratio of y-value to x-value is 2 to 3 for each point.

Suppose Value of is 3a and y value is 2a

So, the coordinate of the point is (3a,2a)

Now we find the x value of the coordinate when value of y is 18.

2a is same as 18

2a = 18

a = $\frac{18}{2}$

a = 9.

Now find the x ordinate

put the value of a=9 into 3a

3a = 3(9) = 27

So the final answer is :

Value of x = 27 when value of y = 18

Answer 2

It is 27 because if you do 9 times 2 you get 18 so you would do 9 times 3 which is the value of x, which is equal to 26
