Answer:

Hi!

Alrighty here we go:

2(9+x)=-5(4-x)

18+2x=-20+5x

Now combine like terms

+20+18+2x=-20+20+5x

38+2x=5x

38+2x-2x=5x-2x

38=3x

x= 38/3

Hope this helped!

A ligament is a band of tough tissue connection bones or holding organs in place
timurjin [86]
<h2><u>Full Question:</u></h2>

Which definition for a ligament did you think was better? Explain. 1- A ligament is made up of tissue that forms a band. 2- A ligament is a band of tough tissue connecting bones or holding organs in place.

<h2><u>Answer:</u></h2>

A ligament is a band of tough tissue connecting bones or holding organs in place is the better definition.

Option B

<h3><u>Step-by-step explanation:</u></h3>

Ligament is a type of connective tissue which develops from the mesoderm. Its actually a tough band containing mostly collagen tissue. Ligament joins two bones which forms a joint.

Ligament is formed of collagen fibres which run parallel to each other and this forms a band. It's very tough and this is why, it can hold bones together.

Ligaments that hold organs are actually pseudo ligaments which are actually folds of peritonium that holds the organs in place.

Solve for z, z−a= z/b , if b≠1
romanna [79]

Answer:

z=\frac{ba}{b-1}

Step-by-step explanation:

There are no numbers, only variables. So solving for "z" would mean we get an expression for z.

The equation given is:

z-a=\frac{z}{b}

We will cross multiply and use distributive property (shown below) to do our algebra and come up with an expression for z, in terms of a and b.

<u>Distributive property:</u>  a(b - c) = ab - ac

So, lets solve:

z-a=\frac{z}{b}\\b(z-a)=z\\bz-ba=z\\bz-z=ba\\z(b-1)=ba\\z=\frac{ba}{b-1}

This is the expression for z.
