Answer: its supposed to be CPCTC but my teacher told us to not put it so i dont know
Step-by-step explanation:
A) The two angles are supplementary and form a linear pair. This means that their combined measure is 180 degrees.
B) 2x + 68 = 180
C) subtract 68 from both sides. 2x = 112. Divide both sides by 2. x = 56.
If we plug 56 back into the equation 2x, we get 112. The if we add 112+68 we get 180, which means that the two are a linear pair.
11 1/7 devided by 7 5/6 would be 1 139/329 you said to hurry so ...
If we want a complex fraction, we can take a simple fraction and multiply it by some other fraction. in out case, these can be obtained if we mupltiply 1/4 by some other fraction for example:
1/2:

Or we could expess one of the numbers as a fraction:

Answer:
173, 339.10
Step-by-step explanation:
Move the decimal from 157,581.00 to the left to give you 10% of 15,758.10.
Add 15,758.10 to 157,581.00 to give you the total from last month.
Or, convert 10% to a decimal.
157,781 x 0.10 = 15,758.10
15,758.10 + 157,581 = 173,339.10
