Solve the expression 2(1.60+7)−4.90
2(1.60+7)−4.90 can be solved by following the order of operations or the PEMDAS rule.
Firstly, within the parentheses, we have 1.60+7 which equals 8.60.
Now let's substitute this value into the expression: 2(8.60)−4.90.
Next, we multiply 2 by 8.60, which gives us 17.20.
Lastly, we subtract 4.90 from 17.20: 17.20−4.90 = 12.30.
Therefore, the solution to the expression 2(1.60+7)−4.90 is 12.30.
To solve the expression 2(1.60 + 7) - 4.90, we need to follow the order of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).
First, let's simplify within the parentheses: 1.60 + 7 = 8.60.
Now, we have 2(8.60) - 4.90.
Next, we perform the multiplication: 2 * 8.60 = 17.20.
Now, the expression becomes 17.20 - 4.90.
Finally, we subtract 4.90 from 17.20: 17.20 - 4.90 = 12.30.
Therefore, the value of the expression 2(1.60 + 7) - 4.90 is 12.30.
