0.5x + 0.5 + (x - 25) + 100 + (x - 15) = 540
2.5x + 60.5 = 540
2.5x = 540 - 60.5
2.5x = 479.5
x = 479.5/2.5
x = 191.8 <===

so ur angles are :
100 <==
x - 25 = 191.8 - 25 = 166.8 <==
1/2 = 0.50 <==
1/2x = 0.5(191.8) = 95.9 <==
x - 15 = 191.8 - 15 = 176.8 <==

check..100 + 166.8 + 0.50 + 95.9 + 176.8 = 540
                                                            540 = 540 (correct)

a ABC company stock dropped from 25 3/8 to 22 1/4 during a one month period of time so how much stock fall during this period of
OLEGan [10]
First, let's convert the mixed fraction into an improper fraction (trust me, mixed fraction are pretty much the worst things to deal with, especially with higher level math):
25 \frac{3}{8} =  \frac{203}{8}
22 \frac{1}{4} =  \frac{89}{4}

Then, to subtract, since you need a common denominator, I would multiply the second fraction by 2 to get:
2 (\frac{89}{4} ) =  \frac{178}{8}

Now that we have a common denominator, we are ready to subtract:
\frac{203}{8} -  \frac{178}{8} =  \frac{25}{8}

Since that's the most simplified form, and you have been asked the question in a mixed fraction form, let's convert that to a mixed fraction. The remainder of the numerator divided by the denominator is 1, and the quotient is 3. The denominator stays the same. So, this is what results:
3 \frac{1}{8}

And that's your answer: 3 \frac{1}{8}

Hope this all makes sense. If anything doesn't, feel free to tell me!

Step-by-step explanation:

What we will do is evaluate each of the statements:

Eduardo bought 3 liters of water. This statement may be true, because he was able to buy the water for multiple people or for another use.

2,750 milliliters of sports drink. It is false because the quantity is too small to drink.

2.25 liters of juice. As in the case of water, it can be true if it is to be taken in a group.

denis-greek [22]

Answer:

1 \frac{1}{3}

Step-by-step explanation:

1/4cake=1/3cup

Now times both sides by 4

\frac{1}{4} x \frac{4}{1}=1 cake

\frac{1}{3} x \frac{4}{1}=\frac{4}{3} which equals 1 \frac{1}{3}

What is the end behavior of the graph shown below
jasenka [17]

Answer:

  D

Step-by-step explanation:

The end behavior is found by following the arrows on the graph. Here, the right end of the curve tends to infinity in both x- and y-directions.

The left end of the curve tends to negative infinity as the value of x approaches 0 from above.

These observations are summarized in the attachment.
