C. 2.25
Step-by-step explanation:
The following information is missing: J is at (-3, 4). K is at (4,-2).
The x value for point L such that JL and KL form a 3:1 ratio is obtained as follows:
m/(m+n)*run + xJwhere ratio m:n givesfraction m/(m+n), run is the distance over x-axis between J and K, and xJ is the x-coordinate of J.
ratio 3:1 means: m/(m+n) = 3/(3+1) = 3/4run = 4 - (-3) = 7xJ = -3Replacing into the equation:
m/(m+n)*run + xJ = 3/4*7 + (-3) = 2.25

The correct answer is x = 2/5
Step-by-step explanation:
It is given an expression,
1/4x = 5/8
To solve the expression
The given expression is 1/4x = 5/8
(Cross multiply both sides we get)
8 = 5 * 4x
8 = 20x
20x = 8
x = 8/20
x = 2/5
Therefore the value of x = 2/5
The correct answer is x = 2/5
