Answer:

c=9

Step-by-step explanation:

Let's solve your equation step by step:

  1. add 6 on both sides
  2. divide 1.5 from the product of 6 and 7.5 (aka 13.5)
  3. you will get C
  4. put 9 in for C.
<h2>1.5c-6=7.5</h2>

1. 1.5c-6+6=7.5+6

1.5 1.5c=13.5

2.\frac{1.5c}{1.5c}=\frac{13.5}{1.5c}

3. C=9

1.5(9)-6=7.5

13.5-6=7.5

Simplify the expression (8x^3y^2/4a^2b^4)^-2
icang [17]
Simplify the following:
((8 x^3 y^2 a^2 b^4)/4)^(-2)
8/4 = (4×2)/4 = 2:
(2 x^3 y^2 a^2 b^4)^(-2)
Multiply each exponent in 2 x^3 y^2 a^2 b^4 by -2:
(x^(-2×3) y^(-2×2) a^(-2×2) b^(-2×4))/(2^2)
-2×3 = -6:
(x^(-6) y^(-2×2) a^(-2×2) b^(-2×4))/2^2
-2×2 = -4:
(y^(-4) a^(-2×2) b^(-2×4))/(2^2 x^6)
-2×2 = -4:
(a^(-4) b^(-2×4))/(2^2 x^6 y^4)
-2×4 = -8:
b^(-8)/(2^2 x^6 y^4 a^4)
2^2 = 4:
Answer: 1/(4 x^6 y^4 a^4 b^8) thus the answer is A

9x - 3 = 7 (x + 3) + 2n<br><br>answer and ur marked brainly master​
Anna007 [38]

Hey there!

9x - 3 = 7(x + 3) + 2n

➡️ 9x - 3 = 7(x) + 7(3) + 2n

➡️ 9x - 3 = 7x + 21 + 2n

ADD -7x to BOTH SIDES

2n + 7x + 21 + (-7x) = 9x - 3 + (-7x)

SIMPLIFY IT!

2n + 21 = 2x - 3

ADD -21 to BOTH SIDES

2n + 21 + (-21) = 2x - 3 + (-21)

SIMPLIFY THIS AS WELL!

2n = 2x - 24

DIVIDE 2 to BOTH SIDES

2n/2 = (2x - 24)/2

FINALLY SIMPLIFY THIS LAST STEP!

n = x - 12

Answer: n = x - 12

Good luck on your assignment and enjoy your day!
