-6+5 (1-x) = -3 -7x

Mathematics

Answer:

x=-1

Explanation:

-6+5(1-x)=-3-7x

We move all terms to the left:

-6+5(1-x)-(-3-7x)=0

We add all the numbers together, and all the variables

5(-1x+1)-(-7x-3)-6=0

We multiply parentheses

-5x-(-7x-3)+5-6=0

We get rid of parentheses

-5x+7x+3+5-6=0

We add all the numbers together, and all the variables

2x+2=0

We move all terms containing x to the left, all other terms to the right

2x=-2

x=-2/2

x=-1

Answer:

x= -1

Step-by-step explanation:

1. Expand

-6+5 (1-x) : -5x-1

-5x - 1 = -3 - 7x

2. Add 1 to both sides

-5x - 1 + 1 = -3 -7x + 1

3. Simplify

-5x = -7x -2

4. Add 7x to both sides

-5x + 7x = -7x -2 + 7x

5. Simplify

2x = -2

6. Divide both sides by 2

2x/2 = -2/2

7. Simplify

x=-1

Hope this helped :)

The locations, given in polar coordinates, for two ships are (8 mi, 63º) and (8 mi, 123º). Find the distance between the two shi
Anna35 [415]
We know that

The arrangement forms an isosceles triangle with equal legs of 8 miles.
The angle between the legs is equal to

123-63=60°

 Therefore, the other two angles are
Angles = (180-60)/2 = 120/2 = 60°
It can, therefore, be noted that all angles are equal and thus the resulting triangle is actually an equilateral triangle and thus all the sides are equal.

Hence
the answer is
the distance between the two ships is 8 miles apart

alternative Method
Applying the law of cosines
<span>c²=a²+b²-2*a*b*cos C
</span>where
a=8 miles
b=8 miles
C is the angle between the legs-------> 123-63------> 60 degrees
c is the distance between the two ships
so
c²=8²+8²-2*8*8*cos 60------> c²=64-------> c=√64------> c=8 miles
