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

Explanation:

PMR is a healthy coping skill normally learned in any kind of psychiatric business. For example, I learned PMR while I was inpatient at a behavioral health unit. The way we did PMR was that we'd sit up in our chairs and start from the toes and on up. We squeezed our toes together for a few seconds and then released and then we'd do it a second time. After the toes, it would move up to the feet and we'd use the same process for that and for the rest of the joints.
