The regular price for a pair of jeans is $36. the sale price is 45% off the regular price. What is the sale price of jeans?

Answer:

The numbers can be either -8,-7,-6, or 6, 7, 8.

n(n−1)(n+1)=16(n−1+n+n+1)  

⟹n(n2−1)=16×3n  

⟹n(n2−1)n=48nn  

⟹(n2−1)−48=48−48  

⟹n2−49=0  

⟶(n−7)(n+7)=0  

n  can be  7  or  −7 , so the numbers can be either  −8,−7,−6  

Or

6,7,8

Answer: x=1 and y=3

Step-by-step explanation: hope this help

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equations are given below.

x + 5y = 16        ...1

x + 3y = 10        ...2

Subtract equation 2 from equation 1, then we have

x + 5y - x - 3y = 16 - 10

2y = 6

y = 3

Then the value of the variable 'x' will be given as,

x + 5(3) = 16

x + 15 = 16

x = 1

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

Answer:

j = 61

Step-by-step explanation:

j - 18 = 61

Step One: Add your addend and your total together.

18 + 43 = 61

Step Two/Check: Subtract your original total with one of your original addend to get the second original addend you had before.

61 - 18 = 43

The height at which the ladder touches the building is required.

The height of building where the ladder touches the building is 30.9 feet.

a = Required height

b = Distance between the bottom of the ladder and the base of the building = 8.5 feet

c = Length of ladder = 32 feet

From the Pythagoras theorem we have

[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{32^2-8.5^2}\\\Rightarrow a=30.9\ \text{feet}[/tex]

First, let's solve the subtraction (in parentheses):

[tex]\mathsf{\dfrac{-8\left(2-6\right)}{2}}[/tex]

[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]

Now, let's solve the multiplication. Remember: in multiplication, two negative numbers will give a positive number:

[tex]\mathsf{\dfrac{-8(-4)}{2}}[/tex]

[tex]\mathsf{\dfrac{32}{2}}[/tex]

Finally, let's solve the division:

[tex]\mathsf{\dfrac{32}{2} = 16}[/tex]

A dotted line is not included in the solution so there is no equal sign.

The blue area is to the right of the dotted line so the solution is >

The line crosses the x axis at -2

The answer is : x-y > -2

Answer:You can use the concept of conservation of total mechanical energy (neglecting the air resistance).

So, initially total mechanical energy = gravitational potential energy (kinetic energy is zero because initially there is no velocity).

Final total mechanical energy = kinetic energy (gravitational potential energy is zero because height has become zero).

So, initial mechanical energy = Final mechanical energy

Answer:

X= 2

y = 2

Step-by-step explanation:

y=-2x+6............... equation 1

y=3x-4................... equation 2

from equation 2

y=3x-4

substitute y=3x-4 in equation 1

3x-4=-2x+6

collect like terms

3x+2x=6+4

5x=10

divide both sides by 5

X=2

substitute X=2 in equation 1

y=-2x+6

y=-2(2)+6

y=-4+6

y=2

Step-by-step explanation:

Length of the Circumference

Given a circle of radius r, the length of the circumference, or line surrounding the shape is:

[tex]L =2\pi\cdot r[/tex]

The Earth has a diameter of 7,917.5 miles. The radius is half the diameter:

r=7,917.5/2=3,958.75 miles

Assuming a plane flies around the equator at ground level, the distance it would travel is:

[tex]L =2\pi\cdot 3,958.75\ miles[/tex]

L = 24,873.6 miles
