Add all whole numbers together 6 + 4 + 9 = 19 
Then all fractions together 1/2 + 2/3 + 1/4 = find least common denominator 12 so you get: 6/12 +8/12+3/12 = 17/12 
If the fraction has access like 17/12 convert to fraction so working back words you definitely know 12 will be on bottom so 5 has to be numerator and you left with 1 as a whole number so you get 14/12 >>>1 and 5/12 
Next you add 19 plus 1 5/12 = 20 5/12

So the answer is the last option 20 5/12 yards.

The cash price of a television is $580.

Drupady [299]

Answer:

n=25% or 0.25

Step-by-step explanation:

865= 580(n%)+ 6(120)

865= 580 (n%) +720

865-720= 145

145= 580(n%)

divide both by 580, you get 0.25=n%

Suppose that the relation G is defined as follows.

Serga [27]

G:{3,4,6}->{0,9}

The pairs represent the input (first number in each pair) and the result (second nu.ber in each pair) for the relation G. for example G(3)=9.

The domain is the set of values that the relation can act upon. The range is the set of the values the results can take

Ivenika [448]

Answer:

$\dfrac{5^{n+2}-6\times 5^{n+1}}{13 \times5^{n}-2\times5^{n+1}} = -\dfrac{5}{3}$

Step-by-step explanation:

We are given the expression to be simplified:

$\dfrac{5^{n+2}-6\times 5^{n+1}}{13 \times5^{n}-2\times5^{n+1}}$

Let us take common a term with a power of 5 from the numerator and the denominator of the given expression.

We know that:

$a^{p+q} = a^p \times a^q$

Let us use it to solve the powers of 5 in the given expression.

$\therefore$ we can write:

$5^{n+2} = 5^{n+1}\times 5= 5^n\times 5^{2}$

$5^{n+1} = 5^n\times 5$

The given expression becomes:

$\dfrac{5^{n+1} \times 5-6\times 5^{n+1}}{13 \times5^{n}-2\times5^{n}\times 5}$

Taking common $5^{n+1}$ from the numerator and

Taking common $5^{n}$ from the denominator

$\Rightarrow \dfrac{5^{n+1} (5-6)} {5^{n}(13-2\times5)}\\\Rightarrow \dfrac{5^{n+1} (-1)} {5^{n}(13-10)}\\\Rightarrow -\dfrac{5^{n+1}} {5^{n}\times3}\\\Rightarrow -\dfrac{5^{n}\times 5} {5^{n}\times3}\\\Rightarrow -\dfrac{5}{3}$

$\therefore$ The answer is:

$\dfrac{5^{n+2}-6\times 5^{n+1}}{13 \times5^{n}-2\times5^{n+1}} = -\dfrac{5}{3}$
