Answer:
Snickerdoodles are 0.22$ each and chocolate chip are 0.43$ each
Step-by-step explanation:
using the information in the problem, you can make 2 separate equations: 8x+12y=6.92 and 5x+5y=3.25, let x= the cost of a snickerdoodle and y= the cost of a chocolate chip cookie.
With the 2 equations, we can isolate the y variable of the first equation and simplify which will give us y= -2/3x +6.92/12.
You can now take that equation and plug it into equation number 2:
5x+5(-2/3x + 6.92/12)=3.25.
solve that equation by multiplying 5 through the brackets: 5x-10/3x+34.6/12=3.25
add common terms: 5/3x=4.4/12
find the value of x, you will get x=0.22
plug the value of x (0.22) into one of your equations and solve for the y-value
Answer:
Blue
Step-by-step explanation:
First, we need to find the LCD (Least common denominator)
Rewriting input as fractions if necessary:
1/10, 1/4, 1/5
For the denominators (10, 4, 5) the least common multiple (LCM) is 20.
Therefore, the least common denominator (LCD) is 20.
Now, we convert:
Red Marbles: 1/10 = 2/20
Blue Marbles: 1/4 = 5/20
Yellow Marbles: 1/5 = 4/20
As we can see, blue has the most. Now we have our answer! Good luck!
Answer:

Step-by-step explanation:
Similar shapes also maintain a constant proportion of sides. Therefore, we can set up the following equation:

Solving, we get:

Answer:
A - 25%
B - 100%
C - 75%
Step-by-step explanation:
I'm pretty sure. Hope this helps. If the shape is divided into 4 equal parts, each one would be worth 25%.
