Answer:
undefined because the change in y is zero since they do not change, therefore it is undefined
This question is asking for a list of fractions, that when you pull out common factors, they will all simplify back to the 8/5 fraction.
So if 2 is the common factor, you multiply the numerator and denominator by 2.
2: (8*2)/(5*2)= 16/10
3: (8*3)/5*3)= 24/15
4: (8*4)/(5*4)= 32/20
5: (8*5)/(5*5)= 40/25
10: (8*10)/5*10)= 80/50
Eloise's Potential List:
16/10, 24/15, 32/20, 40/25, 80/50
If you simplify any of these fractions above, you will get 8/5 again.
To work backwards:
80/50: 10 goes into 80, 10 goes into 50= 8/5
16/10: 2 goes into 16, 2 goes into 10= 8/5
Hope this helps! :)
3x - 4y = 35
3x + 4y = 5
------------------add
6x = 40
x = 40/6 which reduces to 20/3
3x - 4y = 35
3(20/3) - 4y = 35
20 - 4y = 35
-4y = 35 - 20
-4y = 15
y = -15/4
solution is (20/3, -15/4)
The scarf was 25% off
20 - 15 = $5
20 divided by 5 = 4
So it was 1/4 off which equals 25%
Answer:
2.5 cm
Step-by-step explanation:
5 Cm is the diameter and the radius is half the diameter so 5/2=2.5 or 1/2
