Question

Решите уравнение, используя основное свойство пропорции: 5,5:7 целых 1/3=4,8:(x+8) ПОМОГИТЕ ОЧЕНЬ НУЖНО!!!!!!!

Answer 1

X+8=7 1/3*4,8;5,5=22/3*48/10*10/55=32/5=6,4
x=6,4-8
x=-1,6

Answer 2

Solving the Equation

To solve the equation using the basic property of proportion, we have:

5.5 : 7 and 1/3 = 4.8 : (x + 8)

To solve for x, we can cross-multiply and then solve for x.

Cross-multiplying gives us:

5.5 * (x + 8) = 7 * 4.8

Simplifying the equation:

5.5x + 44 = 33.6

Subtracting 44 from both sides:

5.5x = 33.6 - 44

5.5x = -10.4

Dividing both sides by 5.5:

x = -10.4 / 5.5

Simplifying further:

x ≈ -1.89

Therefore, the solution to the equation is approximately x = -1.89.

Please note that this solution is approximate due to rounding.
