5(15) = 75
75-10 = 65

Answer: 5=x

Step-by-step explanation:

Ok, so if F(x)=15, then the equation would look like this: 15=5x-10

The next step would be to add the 10 over from the right to the left side to get 25=5x

Now divide both sides by 5 to get the answer.

The volume V of a cone varies jointly as the area of the base B and the height
seraphim [82]

Answer:

h = 9 cm.

Step-by-step explanation:

V = kBh   where k is the constant of variation.

From the given info:

32 = k*16*6 = 96k

So k = 32/96 = 1/3.

So we have the equation of variation:

V = 1/3Bh

When V = 60 B = 20, so:

60 = 1/3 20h

20h = 60 * 3 = 180

h = 180 /20 = 9.
