Solve the expression 2(1.60+7)−4.90 .(1 point) 2(1.60+7)−4.90=
2(1.60+7)−4.90 = 2(8.60) - 4.90 = 17.20 - 4.90 = 12.30
To solve the expression 2(1.60 + 7) - 4.90, follow these steps:
Step 1: Start by simplifying the expression inside the parentheses.
1.60 + 7 = 8.60
Step 2: Multiply the result from Step 1 by 2.
2 * 8.60 = 17.20
Step 3: Subtract 4.90 from the result of Step 2.
17.20 - 4.90 = 12.30
Therefore, 2(1.60 + 7) - 4.90 equals 12.30.
To solve the expression 2(1.60 + 7) - 4.90, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction).
Step 1: Simplify the expression inside the parentheses.
1.60 + 7 = 8.60
Now our expression becomes: 2(8.60) - 4.90
Step 2: Perform the multiplication.
2 * 8.60 = 17.20
Now our expression becomes: 17.20 - 4.90
Step 3: Perform the subtraction.
17.20 - 4.90 = 12.30
So, 2(1.60 + 7) - 4.90 is equal to 12.30.
