Question

1) (x - 23). 14 = 56:3) 205 : (у - 27) = 41;5) 89 : (b + 13) = 7120;​

Answer 1

Решение и ответ:

1) (x - 23)·14 = 56

(x - 23) = 56:14

x-23 = 4

x = 23+4

x = 27

3) 205 : (у - 27) = 41

(у - 27) = 205 : 41

у - 27 = 5

y = 27 + 5

y = 32

5) 89 : (b + 13) = 7120

(b + 13) = 89 : 7120

b + 13 = 0,0125

b = -12,9875

Но скорее всего в условии описка!!!!

Решим пример с более корректным условием:

89 · (b + 13) = 7120

(b + 13) = 7120 : 89

b + 13 = 80

b = 80 - 13

b = 67

Answer 2

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

1. (x - 23) * 14 = 56 Let's simplify the equation: 14(x - 23) = 56 Distribute the 14: 14x - 322 = 56 Add 322 to both sides: 14x = 378 Divide both sides by 14: x = 378/14 x = 27

Therefore, the solution to the equation is x = 27.

3. 205 / (y - 27) = 41 Multiply both sides by (y - 27): 205 = 41(y - 27) Expand: 205 = 41y - 1117 Add 1117 to both sides: 1322 = 41y Divide both sides by 41: y = 1322/41 y ≈ 32.24

So, the solution to the equation is y ≈ 32.24.

5. 89 / (b + 13) = 7120 Multiply both sides by (b + 13): 89 = 7120(b + 13) Expand: 89 = 7120b + 92480 Subtract 92480 from both sides: -92391 = 7120b Divide both sides by 7120: b = -92391/7120 b ≈ -13

Therefore, the solution to the equation is b ≈ -13.
