Answer: x=19

Step-by-step explanation: 2x+8x-10=180

Step 1: Simplify

2x+8x-10=180

2x+8x+-10=180

(2x+8x)+(-10)=180(combine like terms)

10x+-10=180

10x-10=180

Step 2: Add 10 to both sides

10x-10+10=180+10

10x=190

Step 3: Divide both sides by 10

10x/10=190/10

x=19

If z^2 1/z^2= 34 find the value of z^3 1/z^3 , using only the positive value of z 1/z

natima [27]

Hello,

Let's assume

$u=z+ \dfrac{1}{z} \\

u^2=(z+ \dfrac{1}{z} )^2=z^2+2*z* \dfrac{1}{z} + \dfrac{1}{z^2} =34+2=36\\
==\ \textgreater \ \ u=6\\

(z+ \dfrac{1}{z} )^3=(z+ \dfrac{1}{z} )(z^2+z* \frac{1}{z} + \frac{1}{z^2} )\\

=6*(34+1)=210
