Math 8 Q1 (Pre-Algebra) / Exponent Rules
Solve the expression 2(1.60+7)−4.90.(1 point)
To solve this expression, we can use the order of operations (PEMDAS).
First, we need to simplify the expression inside the parentheses:
1.60 + 7 = 8.6
Next, we multiply 2 by the simplified expression:
2 * 8.6 = 17.2
Now, we need to multiply 4.90 by 17.2:
4.90 * 17.2 = 84.28
Therefore, the expression 2(1.60+7)-4.90 equals 84.28.
To solve the expression 2(1.60+7)−4.90, follow these steps:
Step 1: Perform the addition inside the parentheses.
1.60 + 7 = 8.60
Step 2: Multiply the sum by 2.
2 * 8.60 = 17.20
Step 3: Subtract 4.90 from the product obtained in Step 2.
17.20 - 4.90 = 12.30
Therefore, the solution to the expression 2(1.60+7)−4.90 is 12.30.
