Answer:
-3x-2y
Step-by-step explanation:
(-6x+3y)-(-3x+5y)
-6x+3x+3y-5y
-3x-2y
Answer:
4x+5y=74
six 5 credit cources and 11 four credit cources
if u substitute in the value its correct
4(11)+5(6)= 44+30 which is 74
and 11 plus 6 is 17 cources so there you go!
Stratified sampling is the sampling method which is the most appropriate for determining the mean number of students per statistics class in your state.
<h3>What is Stratified sampling method?</h3>
This method involves dividing subjects into subgroups known as strata according to shared features.
To determine the mean number of students per statistics class in your state, the state should be divided into strata based on the area, then some statistics classes are then selected for further analysis so as to determine the number of students per statistics class in the state.
This is therefore the reason why Stratified sampling method was chosen as the appropriate choice.

The answer to this question is -5+9=4
Answer:
2002
Step-by-step explanation:
The main topic of the question is compound interest.
If the percentage increase is 7.5%. Then the decimal multiplier would be 1.075. The 1 in front of the decimal represents the increase. 7.5 in decimal form is 0.075, so we just add the two together to get our decimal multiplier.
Now we do trial and error to see when we reach $700. After we get at least $700, we count how many times we multiplied $500 by the decimal multiplier and onwards to figure out the number of years it took and then add that to 1997. We add it to 1997 because the cost of the Freerange Wireless stock must have also been $500 at the end of 1997. The beginning of 1998 is the same as the end of 1997.
1) 500 x 1.075 = $537.50
2) 537.50 x 1.075 = $577.81
3) 577.81 x 1.075 = $621.15
4) 621.15 x 1.075 = $667.74
5) 667.74 x 1.075 = $717.8205
1997 + 5 = 2002
The value of Mira's stock will reach $700 by the end of 2002 because if we know that she used $500 at the beginning of 1998, that also means the cost of the Freerange Wireless stock was $500 at the end of 1997.
I hope this helps.
