Answer:

Step-by-step explanation:

2) 8=n+3/-2

we cross multiply

n+3=8*(-2)

n+3= -16

n= -16 - 3

n= -19

lets check if we are correct

8=-19+3/-2

8= -16/-2

-16/-2=8

4) 9=x/2+6

we first calculate the fraction

x/2+6

L. c. m is 2

x/2+6/1=4x + 8/2=12x/2

2 times 2=4 plus x = 4x

2 times 1 =2 plus 6= 8

thats how i got 4x + 8/2

back to the question

9=12x/2

cross multiply

12x=9*2

12x=18

x=18/12

we will use 2 to divide it

9/2

3 will divide

3/2

x=3/2

4(3x^2y^4)^3 / (2x^3y^5)^4

tatyana61 [14]

Solving the expressions $\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$ we get $\frac{27}{4x^{6}y^{8}}$

Step-by-step explanation:

We need to Solve the expression: $\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$

Solving:

$\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$

$=\frac{4(3^3x^6y^{12})}{(2^4x^{12}y^{20})}\\=\frac{4(27x^6y^{12})}{(16x^{12}y^{20})}\\=\frac{108x^6y^{12}}{16x^{12}y^{20}}$

Applying exponent rule: $\frac{x^a}{x^b}=x^{a-b}$

$=\frac{108x^{6-12}y^{12-20}}{16}\\=\frac{27x^{-6}y^{-8}}{4}$

Another exponent rule says: $x^{-a}=\frac{1}{x^a}=$

$=\frac{27}{4x^{6}y^{8}}$

So, solving the expressions $\frac{4(3x^2y^4)^3}{(2x^3y^5)^4}$ we get $\frac{27}{4x^{6}y^{8}}$

nignag [31]

Answer:

10 points the explantion is below

Step-by-step explanation:

Bob scored 35 points and Lilla scores 15 less so you start with 35 - 15. Then you want to divide 20 by 2 because Carol scored half as much as Lilla. Your equation is ( 35-15) / 2 = 10
