hard question
Step-by-step explanation:
Answer:
Number of ducks = 37
Number of pigs = 18
Step-by-step explanation:
Let,
x be the number of ducks
y be the number of pigs
According to given statement;
x+y=55 Eqn 1
2x+4y=146 Eqn 2 (As ducks will have 2 legs and pigs will have 4)
Multiplying Eqn 1 by 2
2(x+y=55)
2x+2y=110 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2x+4y)-(2x+2y)=146-110
2x+4y-2x-2y=36
2y=36
Dividing both sides by 2
Putting y=18 in Eqn 1
x+18=55
x = 55-18
x = 37
Hence,
Number of ducks = 37
Number of pigs = 18
Answer:
Step-by-step explanation:
the current ages:
father= 32 yrs old
son=5 yrs old
-------
4(5+x) = 32+x
20+4x = 32+x
4x-x = 32–20
3x =12
x = 12/3
x = 4 years
------------------------------------
after the 4 years later the farther age will be 36 ( 32+4 = 36)
the son will be 9 ( 5+4= 9 years)
the x presents how the father will be after 4 times the age of the son
Answer:
The unit cost per ounce for turkey skylar is $ 0.316
Step-by-step explanation:
The total amount of sliced turkey = 5 pounds + 4 ounces
The total cost of turkey slice = $26.88
Now, as we know
1 pounds = 16 ounces
∴ 5 pounds = 16 × 5 = 80 ounces
So, the total amount is 5 pounds + 80 pounds = 85 pounds
∵ 85 pounds of turkey sliced cost $ 26.88
∴ 1 pounds of turkey sliced cost $ = $ 0.316
Hence the unit cost per ounce for turkey skylar is $ 0.316 Answer
X= 4y+4/3yz this is they solution
