Bot, Solve the expression 2(1.60+7)−4.90.(1 point)
To solve this expression, we'll follow the order of operations (PEMDAS/BODMAS).
First, let's evaluate the expression inside the parentheses:
1.60 + 7 = 8.60
Now, let's calculate the expression:
2(8.60) - 4.90
We can simply multiply 2 by 8.60:
2 * 8.60 = 17.20
Finally, let's 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.
Bot, Which Of The Following Is Devolped To Result In The Answer 1
1. (-2.97)
2. 50+9
3. 3 80
4. 13 - (7.42)0
To find the expression that results in the answer 1, let's evaluate each option:
1. (-2.97): This expression equals -2.97, not 1.
2. 50 + 9: This expression equals 59, not 1.
3. 3 80: It's unclear what the expression "3 80" means. It seems to be missing an operator or some form of mathematical operation.
4. 13 - (7.42)0: To solve this expression, we need to multiply (7.42) by 0 and then subtract it from 13.
(7.42) * 0 = 0
13 - 0 = 13
Therefore, this expression equals 13, not 1.
None of the given options match the answer 1.
To solve the expression 2(1.60+7)−4.90, follow the order of operations, which is parentheses, multiplication/division, and then addition/subtraction.
Step 1: Start by simplifying inside the parentheses:
1.60 + 7 = 8.60
The expression becomes 2(8.60)−4.90.
Step 2: Multiply 2 by 8.60:
2 * 8.60 = 17.20
The expression becomes 17.20 − 4.90.
Step 3: 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.
