Answer:
Step-by-step explanation:
let workers=n
time=t(weeks)
t=k/n ,where k is constant .
when t=8,n=3
8=k/3
k=24
t=24/n
n 2 4 6 12
t 12 6 4 2
Answer:
8x² - 15y² + xy
Step-by-step explanation:
(4x + 5y) (2x - 3y) + 3xy
multiplying the terms in brackets
(4x) (2x - 3y) + (5y) (2x - 3y) + 3 xy
multiplying with each terms inside the bracket
(4x)(2x) - (4x) (3y) + (5y) (2x) - (5y) (3y) + 3xy
doing the product each of the pair of terms
8x² - 12xy + 10xy - 15y² + 3xy
taking the sum of terms with coefficient "xy"
8x² - 15y² -2xy + 3xy
8x² - 15y² + xy

Answer:
-7
Step-by-step explanation:
2-3(3)=-7
3x - 2 < 12
3x < 12 + 2
3x < 14
x < 14/3
x < 4 2/3......whole-number value = 4
