Hi!
To solve this problem you can set up a proportion (I like doing it this way) or you can just do:
First deal:
(24/3)*5 = 40 dollars
Second deal:
(24/4)*6 = 36 dollars
Finding money saved:
40-36 =4
They will save 4 dollars buying the second 4 for 6 dollars deal!
Answer:
y = -7.5x
Step-by-step explanation:
<u>-45 + 15</u>
6 - 2
= -7.5
Answer: 17500 meters
Step-by-step explanation: 7 times 2.5 is 17.5 and one meter is 0.001 kilometers so
17.5 in meters is 17500.
1st is 1 1/2 2nd is 2 and 3 is 2
So x is from -3 to 10, including -3, but not including 10
so that would be the interval
[-3,10)
remember, the brackets [] are inclusive meaning ≤ and ≥
parenthasees () are not inclusive maning < and >
[-3,10)
