Answer:
7 hr * 12 days = 84 hours
10*84 = 840 man-hrs to build the wall
----
14 men * 8 hr = 112 man-hrs/day
840/112 = 7.5 days
Step-by-step explanation:
Hello!
multiple of 12 include:
1, 2, 3, 4, 6, and 12
1 * 12 = 12
2 * 6 = 12
3 * 4 = 12
I hope this helps, and have a nice day!
2x + 12y = - 1
12y = - 2x - 1
y = - x/6 - 1/12
m1 = - 1/6
m1 × m2 = - 1
- 1/6 × m2 = - 1
m2 = 6
y = 6x + c , ( 0,9 )
9 = 6( 0 ) + c
c = 9
y = 6x + 9
