X+6 /3 = 2+x-2/5

1 answer:

3 0

We can treat this problem like you regularly subtract fractions. First find the common denominator, which is 15.

So:

5(x+6)/15 = 30/15 + 3(x-2)/15

(5x+6)/15 - (30/15) - (3x - 6)/15

As you already know the answer, I'm assuming you can do the rest.

Hope this helps!

loris [4]

Answer:

30.7 km

Step-by-step explanation:

The distance between the two fires can be found using the Law of Cosines. For ΔABC in which sides 'a' and 'b' are given, along with angle C, the third side is ...

c = √(a² +b² -2ab·cos(C))

The angle measured between the two fires is ...

180° -(69° -35°) = 146°

and the distance is ...

c = √(11² +21² -2(11)(21)cos(146°)) ≈ √945.015

c ≈ 30.74

The straight-line distance between the two fires is about 30.7 km.

Answer:

Step-by-step explanation:

surface area = 2πrh + 2πr²

where r = 2 miles radius

h = 3 miles

<u>plugin values into the formula</u>

surface area = 2πrh + 2πr²

= 2π (2) 3 + 2π (2)²

= 37.699 + 25.133

= 62.832 mi.²
