Answer:
passenger train is travelling 58mph
freight train at 38 mph
Step-by-step explanation:
first i listed all the numbers that could divide 190
1,2,5,10,19,38
& then it was simple from there .
next all i had to do is add 20 to each number and then see if that number could divide 290
38 could divide 190
38+20 =58
290÷58=5
190 ÷38=5
it took the passenger train 5 mins to travel 290 miles while the freight train took 5 mins to trvel 190 miles
Answer:
x+27
Step-by-step explanation:
Let's simplify step-by-step.
4(x+3)+3(5−x)
Distribute:
=(4)(x)+(4)(3)+(3)(5)+(3)(−x)
=4x+12+15+−3x
Combine Like Terms:
=4x+12+15+−3x
=(4x+−3x)+(12+15)
=x+27
Hope you find this Useful!
The answer is 12. I would do it by setting up a proportion:
8 = x
10 15
Then cross multiply to get
10x=8*15
10x=120
x=12

Hello from MrBillDoesMath!
Answer:
x^3 - 6 x^2 - x + 6
Discussion:
The polynomial is
(x-1) (x - (-1)) (x-6) =
(x-1)(x+1)(x-6) = => as (x-1)(x+1) = x^2 - 1
(x^2-1)(x-6) =
x^2(x) - 6 x^2 - 1x + 6 =
x^3 - 6 x^2 - x + 6
Thank you,
MrB
