If your trying to find x, distribute 2(x+6), which is by multiplying 2 times x, which is 2x and 2 times 6, which is 12. So your left off with 4x+2=2x+12. In order to find x, we have to move the 2 to the right, which will give us 2x+10 and then move 2x to the left to give us 2x=10. Divide both sides by 2, and x= 5.
49/2= 24.5
Z=24.5
Since you need to get rid of the 2 just divide 49 by 2 and that's what Z equals
45 × 13 = 585
Which is exactly how much he'd need to pay back his sister and buy the bike. So, it would take him 13 weeks.
The sample % of these two populations would be 100/size (of student body at each school) x 100 so this would compare the two student bodies preferences for the particular type of candy bar. However, the actual % of the whole student body at each school would be a factor also. If the high school only had 200 students then this would be 50% representative but if the middle school had say 500 students this would only be 20% representative so this would have to be taken into account too. It might be more representative to have the same % of the student bodies respectively for the sample.
Answer:
for the first box the answer is 4x but I dont know the y intercept
Step-by-step explanation:
get 2 points the do y2-y1/x2-x1 then you get your x
