Commutative property of addition because the commutative property of addition states that the order can change without affecting the sum.
Answer:
18 : 3
Step-by-step explanation:
Basic proportionality question. All we need to here is to expression the given fractions (
, and
) as a fraction itself, and hence expressing the ratio we need to get, in fraction form.
- So, we have expressed this in a fraction, which we want to reduce
- The fractions have been taken as improper fractions
- Now we took the inverse fraction, through multiplication
- 35 and 35 cancel out, leaving us with the simplified fraction 18 / 3
_____
So now we have 18 / 3, the ratio in fraction form. The scale is thus 18 to 3, or in other words 18 : 3.
Hope that helps!
Both Coordinates should be negative
Answer:
Package 3
Step-by-step explanation:
Package 1,
No. of plates = 5
Cost = $38.75
Cost of 1 plate = ![\dfrac{38.75}{5}=\$7.75](https://tex.z-dn.net/?f=%5Cdfrac%7B38.75%7D%7B5%7D%3D%5C%247.75)
Package 2,
No. of plates = 8
Cost = $58
Cost of 1 plate = ![\dfrac{58}{8}=\$7.25](https://tex.z-dn.net/?f=%5Cdfrac%7B58%7D%7B8%7D%3D%5C%247.25)
Package 3,
No. of plates = 14
Cost = $94.5
Cost of 1 plate = ![\dfrac{94.5}{14}=\$6.75](https://tex.z-dn.net/?f=%5Cdfrac%7B94.5%7D%7B14%7D%3D%5C%246.75)
The cost of 1 plate in package 3 is the least. It means she should buy package 3.
