Answer:

(-b-81)/6=a

Step-by-step explanation:

3b−2a-17 = 4a+4b+64

3b-4b-17-64=4a+2a

-b-81=6a

(-b-81)/6=a

Which of the following is NOT true? Question 19 options: (3x2y5)3=27x6y15 (1000x12y20z−3)0=1 52‾‾√3=523 42×43= 165

Answer:

Step-by-step explanation:

Lets try to simplify each to check which one is incorrect so it will be NOT true

first one is :

distribute the exponent so :

$(3x^2y^5)^3 =3^3x^{2*3}y^{5*3}$

$27x^6y^{15}$ CORRECT

Second one is :

$(1000x^{12}y^{20}z^{-30})^{0} =1$

CORRECT because anything raised to exponent 0 is 1 .

Last one is :

$4^2 *4^3 = 4^{2+3}\\=4^{6}\\=(4)^{2*3}\\=16^{3}$

so Last is INCORRECT
