Question

If x = 10, what’s the value of “z” in the equation, z = (x^3 / 5) – 12 ?

Answer 1

z = 188

Explanation:

Solve for z by plugging the value of x into the equation. Remember x=10, so any time you see an x in the equation, replace it with a 10.

`z=((x^(3) )/(5) ) - 12`

`z=((10^(3) )/(5) ) - 12`

`z=((1000)/(5)) -12`

`z=(200)-12`

`z=188`

Answer 2

Answer:188

Explanation:

z = (x^3 /5) - 12

Since x= 10, we input 10 wherever we see x

Z = (10^3 / 5) -12

Using BODMAS, we find the value of 10^3 , then we divide and then we minus

Z= (1000/5) -12

=200 -12

z= 188
