Answer:
1.6 dozen cookies per an hour
Step-by-step explanation:
2 1/2 divided by 2 1/2 gives you 1 hour and 4 divided by 2 1/2 gives you 1.6 dozen cookies
17.8 multiplied by 2 is 35.6
9.5 multiplied by 2 is 19
Now you take both of them and add them together.
35.6 + 19 = 54.6
Your answer should be 54.6 inches of ribbon.
Hope this helps.

Since x+y equals 5 that means x is 3 and y is 2 because 3+2=5. So now plug it in, 2(3)+3(2). Two multiplied by three is 6 and three times two is 6. So now it’s 6+6 which equals 12. So it’s 2(3)+3(2)=12
