Answer:
489.6
Step-by-step explanation:
6 x 6 x 2 x 4 x 1.7
6 x 6 = 36
36 x 2 x 4 x 1.7
36 x 2 = 72
72 x 4 x 1.7
72 x 4 = 288
288 x 1.7 = 489.6
z=3. If z varies inversely as w, and z=4 when w=9, then when w=12 the value of z is 3.
The key to solve this problem is using reverse proportionality, in which two magnitudes a and b are inversely proportional when there is a constant k such that
a⋅b=k, where constant k is called the proportionality constant.
Then if z varies inversely as w, and z=4 when w=9
z.w=k -------> 4.9=k -------> k=36
So, let's find z when w = 12. With k = 36
z.w=K, clear z from the equation
z=k/w -------> z=36/12 -----> z=3
Answer:
x = - 1
Step-by-step explanation:
6(x − 2) = −18
6x - 12 = - 18
6x = - 18 + 12
6x = - 6
x = - 1
