Hello! To find out the amount of ceramic chickens he has in total, we can write and solve a proportion. Set it up like this:
11/x = 10/100
This is because 11 was just the 10% given as gifts, and we are looking for the total amount. Cross multiply the values in order to get 1,100 = 10x. Divide each side by 10 to isolate the x. 1,100/10 is 110. Let's check. 110 * 10% (0.1) = 11. There. x = 110. Cam has 110 ceramic chickens total.
To solve this problem you must apply the proccedure below:
1. Let's call:
x: hot dogs.
y: hamburguers.
2. Then, you must make a system of equations, as below:
5x+4y=12.25 (i)
4x+5y=12.50 (ii)
3. Now, you can solve the system of equation as below:
5x+4y=12.25
x=(12.25-4y)/5
4x+5y=12.50
4((12.25-4y)/5)+5y=12.50
y=1.5
4x+5y=12.50
4x+5(1.5)=12.50
x=1.25
4. Therefore, the answer is:
The cost of one hot dog is $1.25 and the cost of one hamburguer is $1.50
Answer:
Step-by-step explanation:
Try using Symbolab, I use it all the time it gives the correct answer and it gives good explanations (this isn't a sponsor I've just been using it since the 6th grade lol).
Answer:
Slope: -3
Y intercept: (0, 9)
X intercept: (3, 0)
Step-by-step explanation:
In the equation y = mx + b, m is the slope and b is the y intercept.
Since the equation is y = -3x + 9, m is -3 and 9 is the y intercept.
So, the slope is -3 and the y intercept is at (0, 9)
To find the x intercept, plug in 0 as y and solve for x:
y = -3x + 9
0 = -3x + 9
-9 = -3x
3 = x
So, the x intercept is at (3, 0)
Your answer is ....
8(n-3) = 64
