Semenov [28]3 years ago

earrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  

                    p*x+57-(-75*x+q)=0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Unless there is none then in that case there very well may be infinite solutions

What is the volume of this triangular pyramid?<br> 9 cm<br> 7 cm<br> 8 cm
Finger [1]

Answer:

  84 cm³

Step-by-step explanation:

The volume of a pyramid is given by the formula ...

  V = 1/3Bh

where B is the area of the base.

__

The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...

  A = 1/2bh

  A = 1/2(8 cm)(7 cm) = 28 cm²

Then the volume of the triangular pyramid is ...

  V = 1/3(28 cm²)(9 cm) = 84 cm³

the length of a rectangle is 4 meters longer than the width. if the area is 22 square meters , find the rectangle dimension
Readme [11.4K]

Let breadth be x

  • Length=x+4

We know

\boxed{\sf Area_{(Rectangle)}=Length\times Breadth}

\\ \sf\longmapsto x(x+4)=22

\\ \sf\longmapsto x^2+4x=22

\\ \sf\longmapsto x^2+4x-22=0

  • By solving

\\ \sf\longmapsto x=-2\pm\sqrt{26}

It doesnot have any real roots

Which order pair is a solution to the system of linear equations -4+y=8 and x-5y=17?
andreev551 [17]

Hello!

To find this ordered pair, we solve for x and y and put them together in an ordered pair.

-4+y=8

x-5y=17

Let's solve the first equation for y.

y= 12

Now, let's plug 12 into the second equation for y.

x-5(12)=17

x-60=17

x=77

Therefore, our ordered pair is (77,12)

I hope this helps!
