Question

7,2 · (k - 3,6)= 19,44;​

Answer 1

Ответ:

$6,3$

Пошаговое объяснение:

к-3,6=19,44/7,2

к-3,6=2,7

к=3,6+2,7

к=6,3

Answer 2

To solve the equation 7.2(k - 3.6) = 19.44, we can follow these steps:

1. Distribute 7.2 across the parentheses: 7.2k - (7.2)(3.6) = 19.44

2. Simplify the expression by multiplying: 7.2k - 25.92 = 19.44

3. Move the constant term to the other side of the equation by adding 25.92 to both sides: 7.2k = 19.44 + 25.92

4. Combine the constant terms on the right side: 7.2k = 45.36

5. Solve for k by dividing both sides by 7.2: k = 45.36 / 7.2

6. Perform the division to find the value of k: k = 6.3

Therefore, the solution to the equation 7.2(k - 3.6) = 19.44 is k = 6.3.
