1.solve for p
Mnenie [13.5K]
<h3>1. <u>Answer;</u></h3>

<em>p =-3/2p</em>

<h3><u>Solution;</u></h3>

To solve for P  in the equation;

= 3(p + q ) = p

We open the brackets;

= 3p + 3q = p

Then, we combine the like terms together, we get;

 <em>  3p - p = -3q</em>

<em> Therefore; 2p = -3q</em>

<em>   hence;  p = -3/2q. </em>


<h3>2. <u>Answers</u>;</h3>

<em>b = 19/2</em>

<h3><u>Solution;</u></h3>

To solve for b when the value of a = 3

4a = 2b - 7

we substitute 3 with a in the equation

<em>( 4 × 3 ) = 2b -7</em>

<em>12 = 2b -7</em>

<em>Then, make b the subject</em>

<em>19 = 2b</em>

<em>b = 19/2</em>


<h3>3. <u>Answer;</u></h3>

<em>r =d/t</em>

<h3><u><em>Solution;</em></u></h3>

To solve for r 

d= rt.

In order to get r, we divide both sides by t

<em>d/t = rt/t</em>

<em>r =  d/t</em>


<h3>4. <u>Answer;</u></h3>

<em>Width = 30 units</em>

<h3><u>Solution;</u></h3>

The width of a rectangle with a given perimeter of 90 and length is 15.

The perimeter of a rectangle is given by;

Perimeter= 2(Length + Width)

Thus;<em> Perimeter = 90 , length=15 </em>

<em> 90 = 2 (W + 15)</em>

<em>Dividing both sides by 2,</em>

<em>45 = w + 15 </em>

<em>Subtracting from both sides;</em>

<em>W = 45 -15 </em>

<em>W = 30 </em>

Therefore,<em><u> the width of the rectangle is 30 units</u></em>

What is the effect of an emulsifier on the digestion of lipids
snow_lady [41]

Answer:

Emulsifier generally reduces the surface tension of the lipid  there by helping in the digestion of the lipid molecules.

Explanation:

Bile that is secreted from liver act as emulsifier because the bile helps in the break down of lipid into small molecules to form micelle thereby reducing the surface tension of the lipid molecules.

                  Due the formation of micelle the broken down lipid molecules binds to the active site of the lipase enzyme and get digested to form fatty acid and glycerol.

           Beside digestion Emulsifier Bile also helps in the absoption of lipid from the small intestine.

Shkiper50 [21]

The vector that would be the best choice for cystic fibrosis gene therapy is adeno-associated virus for it has valuable reasons. First, it is huge enough to carry the gene, second, it will infect the right type of tissue, third, it will not cause an immune response and lastly, it infects the particular cells that divide irregularly. Therefore, this vector will definitely treat cystic fibrosis for it can target affected cells, which is a great help in the normal functioning of an organ.
