2 negatives can be converted to a plus sign. -(-x) can be +x or just x.

-54--23

-54+23

<u>23-54=-31</u>

78--4

<u>78+4=82</u>

-48/-6

Now let's pause fer a sec. When a negative is being divided by another negative, the quotient(answer to division problem) becomes a positive.

<u>-48/-6=8</u>

HELP!!!!!
antoniya [11.8K]

Answer: 82°

Step-by-step explanation:

<CDE = far arc - near arc / 2

i.e

<CDE = arcCBE - arcCE / 2

arcCE = 98°

arcCBE = 360° - 98° = 262°

<CDE = 262° - 98° / 2

<CDE = 164 / 2

<CDE = 82°

Therefore the measure of < CDE is 82°

Arrange the number in increasing order<br><br><br> 14.204 14.200 14.240 14.210
Gnesinka [82]

Answer:

14.200,14.204,14.210,14.240

Step-by-step explanation:

To arrange in increasing order, we start from the least number and end on the highest number.

The given numbers are,14.204, 14.200, 14.240, 14.210

We can observe that:

14.200<14.204<14.210<14.240

Therefore the numbers in increasing order is 14.200,14.204,14.210,14.240
