Answer:

The value of the expression is 18.9

Explanation:

The expression is:


\bigg( (4)/(5)+(3)/(5)\bigg)+3.5* 5

The first step is to solve the parenthesis. As both fractions have the same denominator, the numerators must be added:


\bigg( (4+3)/(5)\bigg)+3.5* 5


\bigg( (7)/(5)\bigg)+3.5* 5

The second step is to perform the division between 7 and 5, it is 1.4:


1.4+3.5* 5

The third step is to perform the multiplication between 3.5 and 5, it is 17.5:


1.4+17.5

The last step is to perform the sum, it is 18.9:


1.4+17.5=18.9

Thus, the value of the expression is 18.9.
