Question

Найдите значения каждого выражения, если b=20: b:5 b+56 b+( b-10) ( b+b):5

Answer 1

20:5=4 ; 20+56=76 ; 20+(20-10)=30 ; (20+20):5=8

Answer 2

To find the values of each expression when b = 20, simply substitute b with 20 in each expression and calculate the result. Let's do that:

1. b:5 Replace b with 20: 20 ÷ 5 = 4

2. b+56 Replace b with 20: 20 + 56 = 76

3. b+(b-10) Replace b with 20: 20 + (20 - 10) = 20 + 10 = 30

4. (b+b):5 Replace b with 20: (20 + 20) ÷ 5 = 40 ÷ 5 = 8

So, the values of each expression when b = 20 are:

1. b:5 = 4
2. b+56 = 76
3. b+(b-10) = 30
4. (b+b):5 = 8
