Walkway over the hudson, a bridge that crosses the hudson river in poughkeepsie, is 2.063 kilograms long. Anping bridge, which was built in china 850 years ago, is 2.07 kilograms long. what is the total span of both bridges.

4.133 kilometers

Step-by-step explanation:

From the question, we are informed that walkway over the hudson, a bridge that crosses the hudson river in poughkeepsie, is 2.063 kilograms long and that Anping bridge, which was built in china 850 years ago, is 2.07 kilograms long.

The total span of both bridges will be the addition of both walkway. This will be:

= 2.063 kilometers + 2.07 kilometers

= 4.133 kilometers

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
