For the denominators (7, 21) the least common multiple is 21.

Therefore, the least common denominator (LCD) is 21.

Rewriting the original inputs as equivalent fractions with the LCD:
15/21, 1/21

The variable z is inversely proportional to x. When x is 12, z has the value 1.5833333333333. What is the value of z when x= 18?

7nadin3 [17]

Answer:

Z=1.055

Step-by-step explanation:

Z is inversely proportional to X: $Z=\frac{K}{X}$ Where K is a constant

X=18, Z=1.583333333333 we can find K value

K=Z*X =1.58333333333*12= 19

So, Using X=18 We have the following

$Z=\frac{19}{18}$ = 1.055
