2)4p+3,5=p-24,5;

4р-р=-24,5-3,5

3р=-28

Р=-28:3

Р=-9 1/3

3)9p+30,6=0;

9р=-30,6

Р=-30,6:9

Р=-3,4

4)3p-(10p+12)=51

3р-10р-12=51

3р-10р=51+12

-7р=63

Р=63:(-7)

Р=-9

Answer 2

Let's solve each of the equations step by step:

1. 1/3p = 6:

To solve for p, we can multiply both sides of the equation by 3 to eliminate the fraction:

1/3p * 3 = 6 * 3 p = 18

Therefore, the solution to the equation is p = 18.

2. 4p + 3.5 = p - 24.5:

Let's first simplify the equation by combining like terms. We can do this by moving the p term to one side and the constant terms to the other side:

4p - p = -24.5 - 3.5 3p = -28

Now, divide both sides of the equation by 3 to solve for p:

3p/3 = -28/3 p = -28/3

So, the solution to the equation is p = -28/3.

3. 9p + 30.6 = 0:

To solve for p, we can isolate the variable by moving the constant term to the other side:

9p = -30.6

Now, divide both sides of the equation by 9:

9p/9 = -30.6/9 p = -30.6/9

Simplifying the right side gives:

p = -3.4

Therefore, the solution to the equation is p = -3.4.

4. 3p - (10p + 12) = 51:

Let's simplify the equation by distributing the negative sign inside the parentheses:

3p - 10p - 12 = 51

Combine like terms:

-7p - 12 = 51

To isolate p, we'll move the constant term to the other side:

-7p = 51 + 12 -7p = 63

Divide both sides of the equation by -7:

-7p/-7 = 63/-7 p = -9

Therefore, the solution to the equation is p = -9.

To summarize:

1. p = 18
2. p = -28/3
3. p = -3.4
4. p = -9
