Answer: -x + 4y
Step-by-step explanation:
-3(2x-y) + 2y+2(x+y)
-6x + 3y + 2y + 2x + 2y
-6x + 2x +3y + 2y + 2y
-6x + 5x + 4y
-x + 4y
Answer:
120mph.
Step-by-step explanation:
let s = the speed of the private plane
then
(2s+60) = the speed of the commercial airliner
:
Write a time equation; time = dist/speed
300%2Fs = 750%2F%28%282s%2B60%29%29
cross multiply
750s = 300(2s+60)
750s = 600s + 18000
750s - 600s = 18000
150s = 18000
s = 18000/150
s = 120 mph is the speed of the private plane
then
2(120) + 60 = 300 mph is speed of the commercial airliner
:
:
Check this find the actual time for each
300/120 = 2.5 hrs
750/300 = 2.5 hrs, confirms our solutions
Find the speed of each aircraft
The ratio of the distances flown is 750:300 = 5:2. Since the times are the same, the ratio of the speeds is 5:2. So let the two speeds be 5x and 2x.
The speed of the airliner in mph is 60 more than twice the speed of the private plane:
5x+=+2%282x%29%2B60
5x+=+4x%2B60
x+=+60
The speeds of the two aircraft are 5x = 300mph and 2x = 120mph.
Answer:
I think its 71
Step-by-step explanation:
Well the average between -3 -2 and -1 seems to be -2, so all i do is 95-24 and you get 71, either that or 65. I highly think its 71 though
Answer:
The answer is Option C, Y= x - 2
Hope I helped! :}
1/3 of a cup = 3/9 of a cup. If you have 7/9 of a cup, the most 3/9ths that can fit in it is two 3/9ths, which equals 6/9. 6/9 < 7/9. Another latte would give you 9/9, and 9/9 > 7/9 so that's not possible. So two lattes can be made with 7/9 cups of milk.
