3. decreases only
Step-by-step explanation:
its correct
Answer:
left
Step-by-step explanation:
The question says she used
of it, so she probably used
of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:
- ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
make denominators equal

- ![\frac{4}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B8%7D)
![\frac{2}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B8%7D)
![\frac{1}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D)
Answer:
Step-by-step explanation:
a ) 2
b) 0.2
Answer:
1) 6 (9x - 5)
2) 4 (1 + 6)
Step-by-step explanation:
<u>1.</u>
54x - 30
The greatest common factor is 6, hence take out 6
6 (9x - 5)
<u>2.</u>
4 + 24
The greatest common factor is 4, take out 4
4 (1 + 6)
*I am not simplifying this because as per what is given, I am unsure if one of these numbers is actually a coefficient.
You have 1.63636363636...
0.63636363636... is the repeating part. The first term of 0.63636363636... is 0.63, and the common ratio is 1/100.
a
Thus, the sum of the terms of this series is ----------
1 - r
which in this problem comes to:
0.63 63/100
------------------ = ---------------- = 63/99 = 7/11
1 - 1/100 99/100
And so, 1.63333333 ... = 1 + 7/11 or 18/11
