2. (5.7 – 2.4) = (4.6 - 1.3)
3. 3 - 2 [5.76 - {163 +(4.85-2.22)))​

Answer 1

Answer:

1.3, 2. question is wrong, 3.322.74

Answer 2

Answer:

1. 2.3 + 3.6 - (1.4 + 1.5) = 3.0

2. (5.7 - 2.4) = (4.6 - 1.3) = 3.3

3. 3 - 2[5.76 - {163 + (4.85 - 2.22)}] = 322.74

Step-by-step explanation:

1. 2.3 + 3.6 - (1.4 + 1.5) = 5.9 - 2.9 = 3.0

2. (5.7 - 2.4) = 3.3 and (4.6 - 1.3) = 3.3

3. 3 - 2[5.76 - {163 + (4.85 - 2.22)}]

= 3 - 2[5.76 - {163 + 2.63}]

= 3 - 2[5.76 - 165.63]

= 3 + 2x159.87

= 3 + 319.74

= 322.74
