k/6 + 8 = 5 what does k=?

Answers

Answer:

The answer is k= -18

Step-by-step explanation:

hope this helps

k/6 + 8 = 5

1/6k+8-8=5-8

1/6k=-3

To find I divide both sides by 1/6.

1/6k/1/6=-3/1/6

k= -18

The value of k in the equation k/6 + 8 = 5 is -18.

The given equation is k/6 + 8 = 5 .

We have to find the value of k.

Let us isolate the term with variable k by subtracting 8 from both sides:

k/6+8-8=5-8

k/6=-3

Apply cross multiplication:

k=-18

Hence, the value of k is -18.

Help please! Thanks, answer only if you know how to do this.

Answers

Answer:

2 radians

Step-by-step explanation:

The ratio of the arc length to the circumference is the same as the measure of angle AOB in radians to 2pi. 2pi radians is a full circle. We can now construct an equation, with x being our answer.

[tex]\frac{6}{6\pi } =\frac{x}{2\pi } \\\frac{1}{\pi } =\frac{x}{2\pi }\\1=\frac{x}{2} \\2=x[/tex]

First, we try to simplify both sides. Next, we multiply both sides by pi. Then, we multiply both sides by 2. Finally, our answer is 2, so 2 radians.

what will be the answers to all 3 please help PLEASEEEEEE HELPPPPPPPPPPPPPPPPPPPPPPPPPP please help guyss

Answers

1) -12 meters
2) 28 meters
3) 40 meters apart
A. -12 meters
B. 28 meters
C. 40 meters
Step-by-step explanation:
The surface of the ocean would be 0.
Taking this into account, 12 meters below would be 0 - 12, which is -12.
Therefore A's elevation would be -12.

For the sea bird, 28 meters above the surface, which is again 0, would be 0 + 28. B's elevation is 28.

Since the fish is 12 meters below the surface and the sea bird is 28 meters above the surface, simply add the two numbers up to get a total of 40 meters. C would be 40 meters.

Find the value of x for which r || s.
Then find m<1 and m<2.
m<1 = 79- x
m<2 = 94- 2x

< means angle

Answers

Answer:

x=15

Step-by-step explanation:

79-15=64

94-30=64

The value of x for which r || s will be 15.

What are Parallel lines?

Parallel lines are those lines that are equidistance from each other and never intersect each other.

Given that;

Lines r and s are parallel to each other.

m ∠1 = 79 - x

m ∠2 = 94 - 2x

Since, Two lines r and s are parallel to each other.

Then, By definition of alternate angles of parallel lines;

m ∠1 = m ∠2

Now, Substitute the given values we get;

m ∠1 = m ∠2

79 - x = 94 - 2x

Subtract 79 both side,

79 - x - 79 = 94 - 2x - 79

- x = 15 - 2x

Add 2x both side,

- x + 2x = 15 - 2x + 2x

x = 15

Thus, The value of x is 15 for which r || s.
