R + t + L = 5(24).....r + t + L = 120
6r + 4t + 3L = 610
r = 2(t + L).......r = 2t + 2L
2t + 2L + t + L = 120
3t + 3L = 120
6(2t + 2L) + 4t + 3L = 610
12t + 12L + 4t + 3L = 610
16t + 15L = 610
16t + 15L = 610
3t + 3L = 120 ...multiply by -5
-------------------
16t + 15L = 610
-15t - 15L = - 600 (result of multiplying by -5)
-------------------add
t = 10
3t + 3L = 120
3(10) + 3L = 120
30 + 3L = 120
3L = 120 - 30
3L = 90
L = 90/3
L = 30
r = 2(t + L)
r = 2(10 + 30)
r = 2(40)
r = 80
so for all the bouquets, there are 80 roses, 30 lillies, and 10 tulips....but there are 5 bouquets...
so each bouquet has :
80/5 = 16 roses <==
10/5 = 2 tulips <==
30/5 = 6 lillies <==
First you have to figure that it sounds confusing but. What you have to do is that 171 is 189 LESS than from one place to another. So just do : 189-171= 18. And then you know 18.
(5b^2 - 3b + 2) + (2b - 4)
Just expand out all the brackets
5b^2 - b - 2
I think you should add do not subract
