First what you want to do is get rid of the parenthesis by solving each expression: -7.9×6.2=-48.98
-4.5+8.2=-12.7
now just add them together: -48.98+(-12.7)=-61.68
So the answer to this expression is -61.68

If 4 more than 4 times a certain number is the same as 4 more than the product of 3 and 4, what is that number?
gtnhenbr [62]

Answer: the number is 3

Step-by-step explanation:

Let the number be represented by x.

If 4 more than 4 times a certain number is the same as 4 more than the product of 3 and 4, it means that

4x + 4 = 4 + 3×4

4x + 4 = 4 + 12

4x + 4 = 16

Subtracting 4 from the left hand side and the right hand side of the equation, it becomes

4x + 4 - 4 = 16 - 4

4x = 12

Dividing the left hand side and the right hand side of the equation by 4, it becomes

x = 12/4 = 3
