16. 5x^3 y^-5 • 4xy^3
20x^4y^-2

20x^4 • 1/y^2

=20x^4/y^2

17. -2b^3c • 4b^2c^2
= -8b^5c^3

18. a^3n^7 / an^4 (a^3 minus a = a^2 same as n^7 minus n^4 = n^3)
=a^2n^3

19. -yz^5 / y^2z^3

= -z^2/y

20. -7x^5y^5z^4 / 21x^7y^5z^2 (divide -7 to 21 and minus xyz)

= -z / 3x^2

21. 9a^7b^5x^5 / 18a^5b^9c^3

=a^2c^2 / 2b^4

22. (n^5)^4

n ^5 x 4
=n^20

23. (z^3)^6
z ^3 x 6
=z^18

What is 19 - 6x = 29
notka56 [123]

Answer:

x = (-5)/3

Step-by-step explanation:

Solve for x:

19 - 6 x = 29

Hint: | Isolate terms with x to the left hand side.

Subtract 19 from both sides:

(19 - 19) - 6 x = 29 - 19

Hint: | Look for the difference of two identical terms.

19 - 19 = 0:

-6 x = 29 - 19

Hint: | Evaluate 29 - 19.

29 - 19 = 10:

-6 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -6 x = 10 by -6:

(-6 x)/(-6) = 10/(-6)

Hint: | Any nonzero number divided by itself is one.

(-6)/(-6) = 1:

x = 10/(-6)

Hint: | Reduce 10/(-6) to lowest terms. Start by finding the GCD of 10 and -6.

The gcd of 10 and -6 is 2, so 10/(-6) = (2×5)/(2 (-3)) = 2/2×5/(-3) = 5/(-3):

x = 5/(-3)

Hint: | Simplify the sign of 5/(-3).

Multiply numerator and denominator of 5/(-3) by -1:

Answer: x = (-5)/3

Goryan [66]
(192+214+250+x)/4=225

 solve for x

(656 + x)/4= 225
656+x = 225*4
656 + x = 900
x = 900 - 656
x= 244
