Question

Bot, Solve the expression 2(1.60+7)−4.90.(1 point)

Answer 1

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

Answer 2

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.

Answer 3

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.
