It's urgent to solve engineering problems with linear equation of one variable!
For a road project, team a will complete the construction in 8 days and team B will complete the construction in 12 days. Now team a and team B will work together for 4 days. Because team a has other tasks, the rest of the project will be completed by team B. how many days does team B have to finish?
1 - (1 / 8 + 1 / 12) times 4 = 1 / 6
1 / 6 divided by 1 / 12 = 2
55 times (33:1 + 22:1-44:1)
55×(1/33+1/22-1/44)
=55×1/11×(1/3+1/2-1/4)
=5×7/12
=35/12
The meeting is a handshake, a total of 28 times, a total of how many people
If there are n people in total, there are:
(1/2)N(N-1)=28
N(N-1)=56
N^2-N-56=0
(N-8)(N+7)=0
N-8 = 0 or N + 7 = 0
N1 = 8, N2 = - 7
So, there are eight
What is 25 ° 36 '* 4, 39 ° 48' + 41 ° 37 '
25°36′*4
=100°144′
=100°(120+24)′
=102°24′
39°48′+41°37′
=80°85′
=80°(60+25)′
=81°25′
