Answer: 13,000\ feet\ long

Step-by-step explanation:

Let be "a" the lenght (in feet) of the Akashi Kaikyo Bridge in Japan  and "g" the lenght  (in feet) of the Golden Gate Bridge in San Francisco.

We can covert from mixed number to improper fraction by multplying the whole number part by the denominator of the fraction and adding this product to the numerator:

1\frac{4}{9}=\frac{(1*9)+4}{9}=\frac{13}{9}

Then, according to the information provided in the exercise:, we can write this equation:

 a=\frac{13}{9}g

Knowing that:

g=9,000

We can substitute this value into a=\frac{13}{9}g to find "a". Then we get:

a=\frac{13}{9}(9,000)=13,000

[(4x + 15) / 5x)] = 1/2
Arada [10]
One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:

<span>[(4x + 15) / 5x)] = 1/2  could be written as:

4x + 15        1
----------- =  ---
     5x           2

Then 8x + 30 = 5x

3x = -30,  and so     x = -10 (answer).  Be certain to check this answer through substitution!

PLEASE HELP 2O POINTS
vovangra [49]
C. The first is a solution, but the second is not.

5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13 
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13

5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution

hope i could help
