Answer: 3

Step-by-step explanation:

5−(4−2−(6−6))

=3

Answer:

Answer:

3

Step-by-step explanation:

Simplify the following:

5 - (4 - 2 - (6 - 6))

6 - 6 = 0:

5 - (4 - 2 - 0)

-0 = 0:

5 - (4 - 2 + 0)

4 - 2 + 0 = 4 - 2:

5 - 4 - 2

4 - 2 = 2:

5 - 2

5 - 2 = 3:

Answer: 3

The swans swam across Evergreen Lake four times. The lake is 3.5 miles wide. How many miles did each swan swim?

How many miles did all the swans swim?

3.5miles * 4 = the swans swam 14 miles each

since i don't know how many swans there are I'm assuming its a pair of swans

in total the swans swam 28 miles

since i don't know how many swans there are I'm assuming its a pair of swans

in total the swans swam 28 miles

14 the swans swam 14 miles each

The sum of 237 and six times the opposite of a number is 405. what is the number? a. -28

b. -24

c. 30

d. 32

The number is 28.

The equation would be:

237 + 6(x) = 405

The problem states that 6 times the opposite of a number, however, since the number sign was not given, we do not know whether it is in a positive or negative form. So we leave it as only x.

237 + 6x = 405

6x = 405 - 237

6x = 168

6x / 6 = 168 / 6

x = 28

To check:

237 + 6 (28) = 405

237 + 168 = 405

405 = 405

The equation would be:

237 + 6(x) = 405

The problem states that 6 times the opposite of a number, however, since the number sign was not given, we do not know whether it is in a positive or negative form. So we leave it as only x.

237 + 6x = 405

6x = 405 - 237

6x = 168

6x / 6 = 168 / 6

x = 28

To check:

237 + 6 (28) = 405

237 + 168 = 405

405 = 405

Answer:

The answer is A.) -28

Step-by-step explanation:

Let x = the number

237 + (-6x) = 405

237 - 6x = 405

-6x = 168

x = -28
