How to solve 8(y+2.4) if y equals 0.3

21.6

Step-by-step explanation:

To solve for expressions with variables, substitute the variable's value is where the variable is in the expression.

The variable is y, and y's value is 0.3

Substitute y for 0.3

8(y+2.4)

= 8(0.3+2.4)

Now solve by following BEDMAS (brackets, exponents, division, multiplication, addition, subtraction).

= 8(0.3+2.4)      <=Solve the brackets by adding

= 8(2.7)    <= multiply

= 21.6

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
