Answer:
34 weeks
Step-by-step explanation:
As given,
Wage of 1 hour = $12
⇒1$ = hour
⇒$3000 = = 250 hour
As given,
1 week = 5 days
And he works
hour in 1 day
⇒5 days = 5× = hours
⇒1 week = hours
⇒1 hour = week
⇒250 hour = = 33.34 weeks ≈ 34 weeks

Short Answer: 315 Total Shoppers: (10/63) Men
Step One
Let the children = C
Let the adults = A
Let the Men = M
Let the Women = W
Let the Boys = B
Let the Girls = G
Let the total number of shoppers = T
Find the Fraction of Children
4/9 T = C
Find the fraction of adults
T - 4/9 T = A
5/9 T = A
Find the Fraction of Women
5/7 A = W
(5/7) (5/9) T = W
(25/63) T = W
Find the Fraction of Men
Note if 5/7 of the adults are women then 2/7 of the adults are men.
2/7 A = M
2/7 5/9 T = M
10/63 = M <<<<<<< Answer for fraction of Men
Find the fraction of Boys. The boys = 1/2 the Men
1/2 M = B
(1/2)(2/7)(5/9)T = B
5/63 T = B
Find The fraction of Girls
(4/9)T - B = G
4/9 T - 5/63 T = G
(28 / 63) T - (5/63/)T = G
(28/63 - 5/63)T = G
(23 /63) T = G
Find the total number of shoppers.
B + 90 = G
(5/63) T + 90 = (23/63) T
90 = (23/63)T - (5/63)T
90 = (18/63)T
90 (63/18) =T
T = 5*63
T = 315 Answer for total number of Shoppers
Note see above for the fraction of men.

Answer:
Step-by-step explanation:
-5x - 10y = 15
<u>-3x + 10y = 25 </u>+
-8x = 40
x = -5
.
Substitute the value of x to one of equations
-5(-5) - 10y = 15
25 - 10y = 15
-10y = 15 - 25
-10y = -10
y = 1
Y is greater than or equal to -6 i believe
