3(m + 2) - 4(2m - 9)
= 3m + 6 - 8m + 36
= 3m - 8m + 6 + 36 (now, we will group like terms).
= -5m + 42.

For which equation is g = 0 not the solution?
Shalnov [3]

Answer:

3g = 30

Step-by-step explanation:

Well, lets check each one to see if any leaves g = 0

12g = 0      (Given)

<em>÷12   ÷12    </em>(Get "g" on its own)

g = 0          (0 ÷ 12 = 0)

We know it is not this one since g = 0

3g = 30    (Given)

<em>÷3     ÷3    </em>(Get "g" on its own)

g = 10       (30 ÷ 3 = 10)

This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.

<em>Just in case, I will do the other options just not as in-depth!</em>

<em />

g + 8 = 8

<em>    -8    -8</em>

g = 0

9g = 0

<em>÷9    ÷9</em>

g = 0

Hope this Helps! :)

If x = 2z and y = 3z, find z
LenKa [72]

Answer:36

Step-by-step explanation:

Let name the missing angle in the triangle w.

We know that x+z+w=180

We also know that z+w=3z=y.

That means that w=2z.

x=2z, so, 2z+2z+z=180

z=36
