Question

(а*16-720):30=8(95-380:b)+35=110

Answer 1

Ответ:

(a * 16 − 720) : 30 = 400 − 392

(a * 16 − 720) : 30 = 8

a * 16 − 720 = 8 * 30

a * 16 − 720 = 240

a * 16 = 240 + 720

a * 16 = 960

a = 960 : 16

Answer 2

Let's solve the equation step by step:

1. Start with the first part of the equation: (а * 16 - 720) / 30 = 8(95 - 380 / b) + 35 = 110

2. Simplify the first part of the equation: (а * 16 - 720) / 30 = 8(95 - 12.6667 / b) + 35 = 110

3. Divide both sides of the equation by 8 to isolate the expression inside the parentheses on the right side: (а * 16 - 720) / 30 / 8 = (8(95 - 12.6667 / b) + 35) / 8 = 110 / 8

4. Simplify further: (а * 2 - 90) / 30 = (95 - 12.6667 / b) + 35 / 8 = 13.75

5. Now, multiply both sides of the equation by 30 to isolate the left side: а * 2 - 90 = 13.75 * 30

6. Simplify the right side: а * 2 - 90 = 412.5

7. Add 90 to both sides to isolate the 'а' variable: а * 2 = 412.5 + 90

8. Simplify the right side: а * 2 = 502.5

9. Finally, divide both sides by 2 to solve for 'а': а = 502.5 / 2 а = 251.25

So, the value of 'а' that satisfies the equation is 251.25.
