if i dont eat for a week how much weight will i gain?​

Answers

Answer:

Your body can maintain itself for a week or two without access to food and water and possibly even longer if you consume water. Those who experience starvation will need to be monitored by a doctor to get back to health following the time period without nourishment to avoid referring syndrome.

Step-by-step explanation:

its not safe dont think about it dude

Answer:

Around 5 pounds

Step-by-step explanation:

While some may think that not eating will make them lose weight, it doesn't. When your body doesn't get the nutrients it needs, it senses danger, and holds on to body fat to help you stay strong.

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

1st box: 2

2nd box: 5

3rd box: 8

4th box: 11

5th box: 14

Step-by-step explanation: Plug in the formula y=3x+5. For example, you plug -1 as x, and you get y=(3)(-1)+5. 3 x -1 is -3, and then you add 5. The final answer is 2. Just do the same thing on the other boxes. Use the x values and plug it in into the formula shown.

All you have to do to find y is plug in the values of x given in the chart and onto the equation

1st: x = -1
y = 3x + 5
y = 3(-1) + 5
y = -3 + 5
y = 2

(-1, 2)

2nd: x = 0
y = 3x + 5
y = 3(0) + 5
y = 0 + 5
y = 5

(0,5)

3rd: x = 1 y= 8

4th: x = 2 y= 11

5th: x = 3 y= 14

Answer:I wrote an equations for A & D

Step-by-step explanation:

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.

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.
