Answer:
144 total cookies
Step-by-step explanation:
First, set up a proportion to find out how many red cookies there are. 4 over 5 is equal to x over 80. Cross-multiply and you will get 64 red cookies. This question is asking how many total cookies there are, so you would add the red and yellow cookies together. 64 plus 80 is 144 total cookies.
A visual example of this is one my mother showed me. She drew a circle and laid out a piece of yarn around it so that it imitated the perfect shape of the circle. She laid out another piece that was as long as the circle's radius. She wrapped the longer piece around the shorter one, and I saw that it could wrap around it three times and still have at least 0.14 units left. I'm not sure if this helps, but the circumference of this circle is 18.84 cm ^2. I hope I answered your question.
Answer:
4/52 chance of selecting a king and 2/52 chance of selecting a black two
Step-by-step explanation:
there are 4 kings in a stack and only 2 black twos
X= 27
Because
3x−4y=65
(3x−4y)+4y=65+4y
3x−4y+4y=4y+65
3x=4y+65
