Either use a calculator or 12!/(3!9!)
Did you substitute in x = 5 y = 12 to find the results?
b. only when x = 0 or y= 0 or they BOTH = 0 are they equal
What do you mean by 'it came out wrong" ??
L = (8 x + 18) / 12
L = 2/3 x + 1.5 would be the sam answer.....did you try that?
w - 7 < 17 Add 7 to both sides of the equation
w < 24
L = (8 x + 18) / 12 feet L = length in feet x = years
Wall area = 4 m x 5 m = 20 m2
20 m2 / 10 m2 /l = 2 liters
-1 -3 just by looking at it...
Sorry....re-read the question....each worker gets paid 9.30 for each hour OR PART OF AN HOUR
so 8.75 hours would round to 9 hours
each would get paid 9 hrs x 9.3 L/hr = ..........
5 builders * 3,5 hr / 1 wall = 17.5 b-hr/wall
(17.5 b-hr/w) / 2 b = 8.75 hrs to build wall with only 2 builders
EACH woud be paid 8.75 hr x 9.30 L/hr = ........
