Question

8р-2р-14,21=75,19 295.1:(п-3)=13 34X(m+1,2)=61,2 15X(к-0,2)=21

Answer 1

6p=75.19+14.21

6p=89.40

p=89.40/6

p=14.90

 

Answer 2

To solve the given equations, let's go through each one step by step:

1. 8р - 2р - 14,21 = 75,19

Combining like terms, we have: 6р - 14,21 = 75,19

To isolate р, we need to move the constant term (14,21) to the other side by adding it to both sides: 6р = 75,19 + 14,21 6р = 89,40

Now, divide both sides by 6 to solve for р: р = 89,40 / 6 р ≈ 14,90

2. 295.1 : (п - 3) = 13

To isolate п, we first need to multiply both sides of the equation by (п - 3): 295.1 = 13(п - 3)

Distribute 13 on the right side: 295.1 = 13п - 39

Move -39 to the left side: 295.1 + 39 = 13п 334.1 = 13п

Finally, divide both sides by 13 to solve for п: п = 334.1 / 13 п ≈ 25.70

3. 34X(m + 1.2) = 61.2

To isolate X, divide both sides of the equation by (m + 1.2): 34X = 61.2 / (m + 1.2)

4. 15X(к - 0.2) = 21

To isolate X, divide both sides of the equation by (к - 0.2): 15X = 21 / (к - 0.2)

Please provide the value of к (the constant) in order to solve equation 4.
