The variable Z is directly proportional to X. When X is 12, Z has the value 228. What is the value of Z when X = 18

Kisachek [45]

Here, z = kx

k = z/x
k = 228/12
k = 19

So, when x = 18,
z = 19 * 18
z = 342

In short, Your Answer would be: 342

Hope this helps!

Pani-rosa [81]

Answer: $\frac{12}{7}\ \text{hours}$

Step-by-step explanation:

Given

New mail carrier takes 4 hours for delivery i.e.

New mail carrier completes $\frac{1}{4}$ part of work in 1 hour

Old mail carrier takes 3 hours for delivery i.e.

mail carrier completes $\frac{1}{3}$ part of work in 1 hour

If they work together, they complete the work in x hours i.e.

$\Rightarrow \dfrac{1}{x}=\dfrac{1}{4}+\dfrac{1}{3}\\\Rightarrow \dfrac{1}{x}=\dfrac{3+4}{12}\\\Rightarrow x=\dfrac{12}{7}\ \text{hours}$
