Question

( a*16-720):30*2=408-392

Answer 1

(16а-720):30×2=16
16а-720:30=8
16а-720=240
16а=960
а=60
ответ 60

Answer 2

(a*16-720):30*2=408-392;
(16a-720):60=16;
16a-720=16*60;
16a-720=960;
16a=960+720;
16a=1680;
a=1680:16;
a=105.

Answer 3

Let's solve the equation step by step:

1. Evaluate the expression on the left side of the equation: (a * 16 - 720) / 30 * 2

2. Simplify the left side: (16a - 720) / 30 * 2

3. Divide both the numerator and denominator by 2: (8a - 360) / 30

4. Now, solve for 'a': (8a - 360) / 30 = 408 - 392

5. Simplify the right side of the equation: (8a - 360) / 30 = 16

6. Cross-multiply to eliminate the denominator: 8a - 360 = 16 * 30

7. Continue solving for 'a': 8a - 360 = 480

8. Add 360 to both sides of the equation: 8a = 480 + 360 8a = 840

9. Finally, divide by 8 to find the value of 'a': a = 840 / 8 a = 105

So the value of 'a' that satisfies the equation is 105.
