Answer: She would need 24 dollars in order to buy 12 ounces.
Step-by-step explanation:
So you take the original information, and you find out how much it costs for each ounce of tea.
Divide $10 by 5ounces
then you get $2 per ounce.
So then you take the 12 ounces and multiply it by $2.
12($2) =$24
The cost of each duck is $ 7 and cost of each chicken is $ 12.
Step-by-step explanation:
Given,
5 chickens and 3 ducks are bought by $ 81
A chicken costs $ 5 more than a duck.
To find the cost of each duck and cost of each chicken.
Let,
The cost of each duck = x
The cost of each chicken = x+5
According to the problem,
5(x+5)+3x = 81
or, 5x+25+3x = 81
or, 8x = 81-25
or, 8x = 56
or, x = 7
Hence,
The cost of each duck = $ 7
The cost of each chicken = $ 7+5 = $ 12
Answer:
4n+6
Step-by-step explanation:
Answer:
x = 0
Step-by-step explanation:
2x + 161 = x + 46 + 115
Subtract x
x + 161 = 161
Subtract 161
x = 0
Answer:
<em>0.15</em>
Step-by-step explanation:
Given the expression that relates the distance and the time with the expression:
d = 0.15t
d is the distance
t is the time
To determine how fast it is flying (Speed), we will need to use the formula
Speed = distance/time
s = d/t
From the given equation we can se that 0.15 = d/t
Comparing this to the general equation, we will see that s = 0.15
<em>Hence the airplane is flying at 0.15</em>
