The lengths of the sides are 24cm, 27cm and 30cm.

Step-by-step explanation:

The ratio of lengths is 8:9:10

Perimeter = 81 cm

Let x be the length of side.

Therefore,

The length of sides is 8x, 9x and 10x.

Perimeter is the sum of 3 sides, therefore,

8x+9x+10x=81\\27x=81

Dividing both sides by 27;

\frac{27x}{27}=\frac{81}{27}\\x=3

Therefore, the lengths of sides are 8(3), 9(3)\ and\ 10(3)

The lengths of the sides are 24cm, 27cm and 30cm.

Help me write "5x-(x-18)= " in those things. 5(-7) &lt;---- (Something like that)<br> X = -7
anzhelika [568]

Answer:

This how you get x. First the way to find the answer is to first put 5x by itself by canceling it out and putting it on the other side of the = which will be

              5x-(x-18)=

          -5x            -5

Which then gets  you this

         -(x-18)=-5x

After that its

x-18=-5x

once you have this subtract x

x-18=-5x

-x     -x

-18=-6x

Then it leaves you the easy part of just dividing

-18/-6x=-6x/-6x

After dividing you get x to be 3

x=3

Once you have x=3  input that number into your equation and you get the answer.

Hope this helps
