Question

7,2/4 = 0,9/(5,6y-5,1)​

Answer 1

Ответ:

y=1

Пошаговое объяснение:

7,2÷4= 1,8

0,9÷(5,6y-5,1)=1,8

0,9:1;8=0,5

(5,6y-5,1)=0,5

0,5+5,1=5,6

5,6y=5,6

y=1

Answer 2

7,2/4=0,9/(5,6y-5,1),y(=)51/56
5,6y-5,1=5/36•3,6
5,6y-5,1=5/36•18/5
5,6y-5,1=1/2
5,6y=1/2+5,1
5,6y=1/2+51/10
5,6y=28/5
y=1, y(=)51/56
y=1

Answer 3

To solve the equation 7.2/4 = 0.9/(5.6y - 5.1), we can begin by cross-multiplying.

Cross-multiplying means multiplying the numerator of the left-hand side by the denominator of the right-hand side, and vice versa.

Starting with the left-hand side: 7.2 * (5.6y - 5.1) = 4 * 0.9

Expanding the left-hand side: 7.2 * 5.6y - 7.2 * 5.1 = 4 * 0.9

Simplifying the equation: 40.32y - 36.72 = 3.6

Next, we can isolate the variable term by moving the constant term to the other side of the equation:

40.32y = 3.6 + 36.72 40.32y = 40.32

Now, we can solve for y by dividing both sides of the equation by 40.32:

y = 40.32 / 40.32 y = 1

Therefore, the solution to the equation 7.2/4 = 0.9/(5.6y - 5.1) is y = 1.
