1.solve for p

Mnenie [13.5K]

<h3>1. Answer;</h3>

p =-3/2p

<h3>Solution;</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;

 3p - p = -3q

 Therefore; 2p = -3q

 hence; p = -3/2q. 

<h3>2. Answers;</h3>

b = 19/2

<h3>Solution;</h3>

To solve for b when the value of a = 3

4a = 2b - 7

we substitute 3 with a in the equation

( 4 × 3 ) = 2b -7

12 = 2b -7

Then, make b the subject

19 = 2b

b = 19/2

<h3>3. Answer;</h3>

r =d/t

<h3>Solution;</h3>

To solve for r

d= rt.

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

d/t = rt/t

r = d/t

<h3>4. Answer;</h3>

Width = 30 units

<h3>Solution;</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; Perimeter = 90 , length=15 

 90 = 2 (W + 15)

Dividing both sides by 2,

45 = w + 15 

Subtracting from both sides;

W = 45 -15 

W = 30 

Therefore, the width of the rectangle is 30 units

Which metabolic pathway would be utilized for sprinting?

Eddi Din [679]

Answer:

b) electron transport chain

Explanation:

During sprinting, muscles need a constant supply of ATPs (the energy currency of cells) to support the continuous movement. The electron transport chain is present in the inner mitochondrial membrane.

Oxidation of NADH and FADH2 through electron transport chain produces proton gradient across the membrane which in turn drives the synthesis of a large number of ATPs to support sprinting.
