Question

Solve by using the steps found in this section. Write your answer in exact, simplified form.
Z varies directly as W.
If Z=46 when W=184, find Z when W is 16.

Help please

Answer 1

Answer:

Z=4

Step-by-step explanation:

46/184=1/4, so we just need to do W/4 to get Z, which is just 16 here.

16/4=4

Answer 2

Answer:

• 4

Step-by-step explanation:

Z varies directly as W:

• Z = kW, where k is the coefficient of variation

We have:

• 46 = k*184

Find k:

• k = 46/184
• k = 1/4

The equation is now:

• Z = (1/4)W

Find Z when W is 16:

• Z = (1/4)*16
• Z = 4
