Answer: 3 days


Step-by-step explanation: It would take 3 days for seven hens to 7 lay eggs because each hen lays an egg each day.

1 hen/1 egg = 3 days

7 hens/7 days = 14 eggs

7 hens/3 days = 7 eggs

Answer:

3 days

Step-by-step explanation:

Three hens lay 3 eggs in 3 days

We have to find the days in which 7 hens lay 7 eggs

Hen/egg=\frac{3}{3}

Hen/egg=1

Using unitary method

1 hen lays 1 egg in 3 days

1 hen lays in 1 day =\frac{1}{3}eggs

7 hens lay 7/3 eggs in 1 day

7 hens lay 1 egg=\frac{3}{7}days

7 hens lay 7 eggs=\frac{3}{7}\times 7

7 hens lay 7 eggs=3 days

Hence, 7 hens lay 7 eggs in 3 days

Write an equation of the line that passes through the given point and is parallel to the given line.
Elza [17]

Step-by-step explanation:

y = 5x - 3 is in slope-intercept form.

The slope of this given line is 5,

=> Parallel line will also have slope 5.

We have y = 5x + c, where c is a constant.

When x = 4, y = 7.

=> (7) = 5(4) + c, c = -13.

Therefore the answer is y = 5x - 13.

Find the distance between the two points. ​(2​,7​) and ​(−18​,22​)
Black_prince [1.1K]

Answer:

d = 25

Step-by-step explanation:

d = sqrt( (y2 - y1)^2 + (x2 - x1)^2  )

d = sqrt( (7  - 22)^2 + (2 - (-18) )^2  )

d = sqrt (  (- 15)^2 + 20^2 )

d = sqrt ( (225) + (400) )

d = sqrt (625)

d = 25

Understanding the Closure Property
Mariulka [41]

Option D:

The sum of any two real numbers is also a real number.

Solution:

<u>Closure property of addition of real numbers:</u>

Sum of any two numbers is also a real number.

i.e., a + b = c

If a and b are real, then c is also a real number.

To find which illustrates the closure property of addition of real numbers:

Option A:

The sum of any two numbers is close to the product of those numbers.

It is not true because it is addition property not product.

Option B:

The sum of any two numbers is close to the difference of those numbers.

It is not true because it is addition property not difference.

Option C:

When you add 1 to a number you get the next closest number.

It is not true by the above definition.

Option D:

The sum of any two real numbers is also a real number.

This is the closure property of addition of real numbers.

It is true.

Hence the sum of any two real numbers is also a real number.

Option D is the correct answer.
