Question

А) 1,2 + а, если а = 12; 0,56; б) 4а -2 , если а= 10; 1,2. в) 3,1 + а, если а = 10; 0,06;

Answer 1

а)1,2+12=13,2

1,2+0,56=1,76

б)4•10-2=38

4•1,2-2=4,8-2=2,8

в)3,1+10=13,1

3,1+0,06=3,16

Answer 2

А) To find the value of 1.2 + a, we need to substitute the given values of a.

1. If a = 12: 1.2 + 12 = 13.2

2. If a = 0.56: 1.2 + 0.56 = 1.76

Therefore, the values of 1.2 + a are: a = 12: 13.2 a = 0.56: 1.76

Б) To find the value of 4a - 2, we need to substitute the given values of a.

1. If a = 10: 4 * 10 - 2 = 40 - 2 = 38

2. If a = 1.2: 4 * 1.2 - 2 = 4.8 - 2 = 2.8

Therefore, the values of 4a - 2 are: a = 10: 38 a = 1.2: 2.8

В) To find the value of 3.1 + a, we need to substitute the given values of a.

1. If a = 10: 3.1 + 10 = 13.1

2. If a = 0.06: 3.1 + 0.06 = 3.16

Therefore, the values of 3.1 + a are: a = 10: 13.1 a = 0.06: 3.16
