Answer:
Step-by-step explanation:
either cow or pigs
Either pigs or cow = 40
(1) Let number of pigs be x
then number of cows >twice of pigs = 2x
number of pigs + number of cows = 40
number of cows = 40 -x
40-x > 2x
40 > 3x
x < 
x < 12.33
nearest integral number is 12
so its 12
so number of pigs will be 12 so that number of cows = 40 -12 = 28
which is more than twice of number of pigs
28 > 2( 12) = 24
(2) number of pigs + number of cows = 40
for x>12
number of cows = 40 -x
x > 12
-x < -12
adding 40 both sides
40-x < 40-12
number of cows <28
Answer:
Helmets-12
Baseballs-32
Step-by-step explanation:
Given the tax rate as 6% and the reduced prices as $2.25/baseball and $22.50/helmet and that the budget is $400:
The new prices are reduced price plus tax:
Let x be the number of groups of 8 baseballs as well as the number of groups of 3 helmets,therefore:
Substitute for x=4 to find the highest number of baseballs and helmets:
Helmets=4x3=12
Baseball=4x8=32
#Price cost will be 12x23.85+32x2.39=362.68 (balance=37.32)
Hence, Shaw can buy 12 helmets and 32 baseballs and still remain with $37.32
Answer:
(h°h)(10) = 10
Step-by-step explanation:
(h°h) = 6-(6-x) = x
h(10) = x
x = 10
Answer:
96 liters
Step-by-step explanation:
Two liters are in each bottle, so that means they sold 12 bottles of oil each day. Multiply that with 8 days to get the answer:
12 × 8 = 96
Ninety-six liters.
Answer:
Step-by-step explanation:
