Answer:

x=6

Step-by-step explanation:

multiply 7 by x and 7 by -4. You get 7x-28=14, add 28 to 14, which is 42. So 7x=42, then divide 7 on both sides, and you get x=6.

Answer:

x = 6

Step-by-step explanation:

7(x-4)=14

Divide both sides by 7

7(x - 4)/7 = 14/7

x - 4 = 2

Add 4 both sides

x - 4 + 4 = 2 + 4

x = 6

|r|=-2 solve the equation and graph the solution if possible

S_A_V [24]

That bracket symbol, with an r in it, means "the absolute value of r".
So r's absolute value is -2 meaning r is two units from zero
r= 2

There are 80 dogs and cats in the animal shelter. The ratio of dogs to cats is 5/11. How many of the animals are dogs

Dima020 [189]

Answer:

25 dogs and 55 cats

Step-by-step explanation:

5/11 ratio, first add those up which you get 16

Then divide the total amount of animals by the ratio-80

80/16 = 5

(5*5)/(11*5)

The answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be

4 $x^{6} y^{-2}$

Step-by-step explanation:

To simplify

$\frac{4(2x^3 y^4 )^4}{2(2x^2 y^6 )^3}$ .

Using exponential law the exponents of variables will be added when multiplied as per rule

we get

$\frac{4[(2^4)(x^{3\times 4}) ( y^{4\times4} )] }{2[(2^3)(x^{2\times3} ) (y^{6\times3} )]}\\$

$\frac{4[(16)(x^{12}) ( y^{16} )] }{2[(8)(x^{6} ) (y^{18} )]}\\\\\frac{64x^{12}y^{16} }{16 x^{6}y^{18} }$

Now by dividing according to exponential rule the exponents of variables will be subtracted as per rule

$(\frac{64}{16} ) x^{12-6} y^{16-18} \\4 x^{6} y^{-2}$

So the answer of 4(2x^3 y^4 )^4/2(2x^2 y^6 )^3 after simplification will be

4 $x^{6} y^{-2}$
