Answer:
Annie's Orange Grove
Step-by-step explanation:
* you need to find out how much each pound of oranges cost at both orchards.
* to do so you take the total amount of money and divide it by the number of pounds you get.
1) 7.25 ÷ 20 = .36
2) 5 ÷12 = .4
* as you can see .36 is less than .4 and therefore is the better deal.
Answer:
1/7 and 1/2
Step-by-step explanation:
The probability of orange marble is 1/7
Probability of tails is 1/2
If you need to add this, then it'll be 1/14
7 x 2 = 14
1 x 1 = 1
Answer:If I’m correct I believe seven you cars for 16.45 would be better
Step-by-step explanation:
Since three cars cost 7.50 you would divide 7.50 to get the cost for each car which would give you 2.50 and since seven cars cost 16.45 you would divide 16.45 by 7 to get the cost of each car which would come out to 2.35 making it a better buy
If you would like to know which unit rate is equivalent to 17 miles per gallon, you can calculate this using the following steps:
17 miles ... x gallon = ?
51 miles ... 3 gallons
x = 17 * 3 / 51 = 1 gallon
17 miles ... x gallon = ?
34 miles ... 4 gallons
<span>x = 17 * 4 / 34 = 2 gallons</span>
The correct result would be: fifty-one miles over three gallons.
1.
The description of set K as <span> {(x, y) | x - y = 5}, means the following:
the elements of set K are pairs (x,y)
such that: x-y=5, that is we can write(x, y) = (x, x-5).
2.
A set of (ordered) pairs is a function, if each of the first coordinates is paired to only 1 specific value, not 2 or more.
for example: {(1,2), (3, 5), (3, 8)} is not a function because 3 is not paired to only one second value, we have (3, 5) but also (3, 8).
whereas, {(-2, 4), (3, 5), (8.1, 17)} is a function, because each first coordinate is unique, we don't see it again in another pair.
3.
Back in our set K, the description of pairs (x,y) as </span>(x, x-5)
makes sure that each x, produces a specific y, for example in K we have:
(5, 0), and we cannot have (5, a value ≠0), because it would not fit the description (x, x-5)
Answer: yes
