Subtracting because "how far" indicates that there is a total and that you need to subtract the term you have from the total to get term 2.
2x+5=12
2x=7
x=3.5
3.5*6=21
21+20=41
Hope this helps :)
To find the mean of this set of data you must add all the numbers together, then divide by the numbers that you have. Since you have 5 numbers you would divide by 5 after adding them together.
1st: ADD!!
20 + 12 + 29 + 15 + 49 = 125
2nd: divide by 5!
125 ÷ 5 = 25
So the mean of this data set is 25.
Good Luck! :)
Answer:
line lntersection Postulate
Step-by-step explanation:
1 purse and 1 watch is 27€
2 purse and 1 watch is 41€
So we can see the watch is constant means 1 watch is every time but purse is increase by 1 in the next expression
So 41-27 = 14€ is one purse
because the watch is every time one, so the next value increase is by purse
1purse and 1watch = 27
We know,
1 purse is 14€
So 27-14=13€ is one watch
We can check by
1 purse is 14 so two purse is 14*2=28
28+13=41
Which is same as they said in second expression
Hope it help you!¡
