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>

Wiskott-Aldrich syndrome is linked with low immunoglobulin G (IgG) and immunoglobulin M (IgM) levels, with normal-to-high immunoglobulin E (IgE) and immunoglobulin A (IgA) levels. Though, young babies in exact may not display classic immunoglobulin irregularities because Wiskott-Aldrich syndrome is linked with attrition in immunologic functions.

riadik2000 [5.3K]

Answer:

The correct answer is - e. Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase)

Explanation:

Phosphoglucose isomerase (phosphohexose isomerase or glucose-6-phosphate isomerase) is an enzyme that catalyzes the conversion of the glucose-6-phosphate to fructose-6-phosphate or fructose-6-phosphate to glucose-6-phosphate.

In the given question there most likely a mutation that takes place in Phosphoglucose isomerase as it is not able to convert glucose to fructose which is a growth defect.
