Answer:

(3.) x = 45

Step-by-step explanation:

Because the lines are parallel and cut by the same line, the angles within are equal as well.

Which means that...

Angle GE = Angle EFD

Therefore (2x-30) = (x + 15)

2x - 30 = x + 15

    +30       +30    (add 30 to both sides to get rid of the -30)

2x = x + 45

-x    -x                   (subtract x from both sides to get rid of the single positive x)

x = 45

nika2105 [10]
This would mean that she has been in school for about 1,000 days. Thus, we need to figure out the amount of days she would have went to school within the week. This would normally be 5 days within the 7. 

5/100 x 1000 is 714.28

When rounded to the nearest ten, it would end up at 710.

A stock was purchased at $15.75 per share, and sold at $19.25 per share.
BARSIC [14]
ANSWER:
B. $3.50


STEP BY STEP EXPLANATION:

We start out with buying the stock for $15.75 then sell it at $19.25. We need to find the difference.

Subtract $15.75 from $19.25

19.25 - 15.75 = 3.50

To check your work add $3.50 to $15.75

15.75 + 3.50 = 19.25
