Answer:
4 and 5
Step-by-step explanation:
Make a system of equations:
x+y=9
x-y=-1
x=9-y
9-y-y=-1
9-2y=-1
-2y=-10
y=5
Since y=5, x must be 4 since 4+5=9 and 4-5=-1
Hope this helped!
Answer:
The estimate is less than the actual length of the CD.
Step-by-step explanation:
Consider the provided information.
Maurice's new CD has 12 songs. Each song lasts between 3 and 4 minutes.
That means the minimum length of the CD should be: 12×3=36 minutes.
The maximum length of the CD should be: 12×4=48 minutes
He estimates that the whole CD is about 30 minutes long.
30 minutes is less than 36 minutes.
That means, the estimate is less than the actual length of the CD.
Hence, the correct statement is: The estimate is less than the actual length of the CD.
C is a non terminating decimal.
a = 0.75
b = 0.8
c = 0.333333 (and will never terminate)
Average is the total of the numbers divided by the amount of numbers.


36 is the answer.
1/4
because 1/2 = 2/4 and 1/4 is smaller :)
1/2 (2/4):
o o o o
1/4:
o o o o
see, less! :)
so the answer is 1/4
