I NEEED HELP WITH THIS MATH

3. they combined like factors incorrectly X=21.5

4. Supplementary means it's equal to 180, not 90. they did it as if the angle was acute. The answer should be 133 degree

5. The two angles are not equal. however, the two angles added together equal to 180.     115+ 5x -10 = 180   X=15

Step-by-step explanation:

3. 8x + 8 = 180

8x + 8 - 8 = 180 - 8

8x = 172

8x/8=172/8

x=21.5

4. 180-47= 133

5. 115 - 10 + 5x = 180

105 + 5x = 180

105-105+5x=180-105

5x=75

5x/5=75/5

x=15

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
