Answer:

135 km

Solve for x: 2/5 = x/24

lord [1]

Answer:

x=9.6

Step-by-step explanation:

We are given the proportion:

$\frac{2}{5}=\frac{x}{24}$

We are asked to solve for x. Therefore, we must isolate x on one side of the proportion.

x is being divided by 24. The inverse of division is multiplication. Multiply both sides of the proportion by 24.

$24*\frac{2}{5}=\frac{x}{24}*24$

$24*\frac{2}{5}=z$

$24*0.4=x$

$9.6=x$

$x=9.6$

x is equal to 9.6 The complete proportion is $\frac{2}{5}=\frac{9.6}{24}$
