Answer:
x: work a woman can do in 1 day
y: work a girl can do in 1 day
Then
2x + 7y =1/4
4x + 4y =1/3
4x + 14y =2/4 (1)
4x + 4y =1/3 (2)
=> Let (1) - (2), 10y =2/4-1/3 <=>10y = 1/6 <=> y = 1/(6x10) = 1/60 (work)
=> From (2),4x = 1/3 - 4x1/60 => 4x = 16/60 => x = 4/60 (work)
=> 1 day, a woman and a girl can do: 1/60+4/60 = 5/60 =1/12 (work)
Then, the day required for a woman and a girl to complete work: 12 days
Answer:
Revenue = Members * (Cost Per Member)
R = (12.500 *8) =
R= 100.000
R = (12.500 - 500) ( 8 + 1)=
R=12000*9=
R=108.000
Step-by-step explanation:
Revenue = Members * (Cost Per Member)
R = (12.500 *8) =
R= 100.000
R = (12.500 - 500) ( 8 + 1)=
R=12000*9=
R=108.000
Where x represents the number of $1 increases
Where x represents the number of $1 increases
Answer:
x = 24
Step-by-step explanation:
Firstly, isolate x by adding 2 to both sides.
9 = 3/8x
Then, multiply 8 to both sides.
72 = 3x
Then, divide both sides by 3.
24 = x
The square root would be 3.4 if rounded to the tenths place
