Jane is asked to buy some chickens, dogs and ducks for her farm. The total number of animals she needs to buy is 50. She has a budget of $1500 to spend on $20/chicken, $50/dog, and $30/duck. Additionally, the number of chickens should be equal to that of ducks. Create a system of 3 equations to model the situation. Assume the number of chickens is x, dogs is y and ducks is z.
Answer:
x = 20, the number of chickens as well as the number of ducks.
........
20 chickens, 20 ducks and 10 Dogs 50-20-20
And...checking
$400 + $600 + $500 = 1500
x the number of chickens as well as the number of ducks
20x + 30x + 50(50-2x) = $1500
-50x = -1000
Step-by-step explanation:
Hope this helps
The system of 3 equations to model the situation are;
x + y + z = 50
20x + 50y + 30z = 1500
x = z
How to write equation?number of chickens = xnumber of dogs = ynumber of ducks = zcost of each chicken = 20cost of each dog = 50cost of each duck = 30Total cost = 1500Total number of animals = 50The equation:
x + y + z = 50
20x + 50y + 30z = 1500
number of chicken = number of ducks
x = z
Therefore, the equations are;
x + y + z = 50
20x + 50y + 30z = 1500
x = z

n - 4 = 3n + 6 Yikesss
Answer: n=-5
Step-by-step explanation:
Answer:
N=-5
Step-by-step explanation:
N - 4 = 3n + 6
Add 4 to both sides
n-4+4=3n+6+4
Simplify
n=3n+10
subtract 3n from both sides
n-3n=3n+10-3n
Simplify
-2n=10
Divide -2 from both sides
-2n/-2=10/-2
Simplify
n=-5
What is 24:28=? 250:400=? 270:30=? 4:80=? 55:33=? 1000:100=? 560:80=? 20:340=?
Plz help ill give u 20 points if u do all of these:)
Step-by-step explanation:
Ok so if you didn't know, : is another way to write / so 24:28 is the same thing as 24 divided by 28. Or if you just wanted to simplify to most, you just want to find the largest common factor and divide it by both.
24:28 = 6:7
250:400 = 5:8
270:30 = 9:1
4:80 = 1:20
55:33 = 5:3
1000:100 = 100:10
560:80 = 7:1
20:340 = 1:17
Answer: 24:28= 6:7
250:400= 5:8
4:80= 1:20
55:33= 5/3
1000:100= 10:1
560:80= 7:1
20:340= 1:17
Step-by-step explanation:
Divide the numbers on each side of the ratio by Common Factors until what's left can't be divided any further.
One example, last one:
20:340 both divisible by 10, so you get 2:34. Both even numbers so divide by 2. You get 1:17. They can't be divided any further to get whole numbers, so that's the answer.
how do you solve this equation 19−4c=17
Answer: Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.
Here's how:
Step-by-step explanation:
19−4c=17
19 - 19 - 4c = 17 - 19 Subtract 19 from both sides 19-19 =0 Cancels on the left
-4c = 17-19 subtract: 17-19 = -2
-4c = -2
-4c/4 = -2/-4 Divide both sides by -4
Negatives divided by Negatives have a Positive quotient -4/-4 =1, Cancels
c = 1/2
