Question

3-0,2a 5-0,3а сравните если а=16

Answer 1

3 - 0,2a = 3 - 0,2 * 16 = 3 - 3,2 = - 0,2

5 - 0,3a = 5 - 0,3 * 16 = 5 - 4,8 = 0,2

Если a = 16 , то

3 - 0,2a < 5 - 0,3a

Answer 2

To compare the expressions when a = 16, we simply need to substitute the value of a into each expression and perform the calculations:

1. Expression 1: 3 - 0.2a Substituting a = 16: 3 - 0.2 * 16 3 - 3.2 Result: -0.2

2. Expression 2: 5 - 0.3a Substituting a = 16: 5 - 0.3 * 16 5 - 4.8 Result: 0.2

Comparing the results:

• Expression 1 (3 - 0.2a) with a = 16 evaluates to -0.2
• Expression 2 (5 - 0.3a) with a = 16 evaluates to 0.2

Therefore, when a = 16, Expression 2 is greater than Expression 1.
