Question

(x+4,2)-5 1/2=3 7/50

Answer 1

1/2 = 5/10 = 0,5

7/50 = 14/100 = 0,14

- - - - - - - - - - - - - - - -

(х + 4,2) - 5,5 = 3,14

х + 4,2 = 3,14 + 5,5

х + 4,2 = 8,64

х = 8,64 - 4,2

х = 4,44

Answer 2

It appears that you have an equation, but it's not entirely clear what you're asking for. To help you further, I'll assume you want to solve for the variable "x" in the equation:

(x + 4)^2 - 5^(1/2) = 3 + 7/50

Let's break it down step by step:

1. Start with the equation:

   (x + 4)^2 - 5^(1/2) = 3 + 7/50

2. Simplify the equation:

   (x + 4)^2 - √5 = 3 + 7/50

3. Add √5 to both sides to isolate the square term:

   (x + 4)^2 = 3 + 7/50 + √5

4. Combine the constants on the right side:

   (x + 4)^2 = 3 + 7/50 + √5

5. Find a common denominator for 3 and 7/50:

   (x + 4)^2 = (150/50) + (7/50) + √5

6. Add the fractions on the right side:

   (x + 4)^2 = (150 + 7)/50 + √5

7. Combine the fractions:

   (x + 4)^2 = 157/50 + √5

8. Now, we want to take the square root of both sides to solve for "x + 4." Remember that when you take the square root of both sides, there can be two solutions (positive and negative square roots):

   x + 4 = ±√(157/50 + √5)

9. Subtract 4 from both sides to isolate "x":

   x = ±√(157/50 + √5) - 4

Depending on the value of √5 and your preference for decimal or exact solutions, you can calculate the approximate values for x.
