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.

Answers

Answer:

C

Step-by-step explanation:

The value of the equation  36 = (x +9) when x=3 is 12. option C is correct.

To evaluate the expression 36 = (x + 9) when x = 3.

we substitute the value of x into the expression:

36 = (3 + 9)

We know that the value of three plus nine is twelve.

Now, we simplify the expression inside the parentheses:

36 = 12

Hence, the value of the equation is 12.

Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You can get $20 per day for helping your neighbor rake lawns. After how many days will your sister earn as much as you?

Answers

Answer:

6 days

Step-by-step explanation:

pay 60 = -60

Let d = the number of days

30d - 60 = sister

20d = me

Equation:

30d - 60 = 20d                    Move 30 to the other side

-30d          -30d

-60 = 20d - 30d                    Combine liked terms

-60 = -10d                                

-10     -10                                Divide

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.

Answers

Answer:

([tex]\frac{2}{3}[/tex], 2 )

Step-by-step explanation:

Given the 2 equations

3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)

6x - y = 2 → (2)

Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is

- 6x - y = - 6 → (2)

Add (2) and (3) term by term to eliminate x

- 2y = - 4 ( divide both sides by - 2 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

6x - 2 = 2 ( add 2 to both sides )

6x = 4 ( divide both sides by 6 )

x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

Solution is ( [tex]\frac{2}{3}[/tex], 2 )

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.
