The equation -3x - 2/5y = 10 is NOT written in proper Standard Form. Rewrite the equation so it's in Standard Form. (Hint: To be in Standard Form the equation can't start with a negative or contain fractions.)
the options are:
A: -15x -5y = 50
B: 15x - 5y = -50
C: 2y = -50
D: 15x - 2y = -50

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
