Question

Помогите упростить и решить:(c+5.4)-(4.9+c)

Answer 1

$(c+5.4)-(4.9+c)=c+5.4-4.9-c=0,5$

Answer 2

(c+5.4)-(4.9+c) =c+5.4-4.9-c =0.5

Answer 3

(c + 5.4) - (4.9 + c)

First, distribute the negative sign to both terms inside the parentheses: c + 5.4 - 4.9 - c

Combine like terms: (c - c) + (5.4 - 4.9)

The c and -c cancel each other out, leaving: 5.4 - 4.9

Finally, subtract 4.9 from 5.4: 5.4 - 4.9 = 0.5

So, the simplified and solved expression is: (c + 5.4) - (4.9 + c) = 0.5
