Answer:
-3 + 5 = 2
-3 + -2 = 1
-2 + -1 = -3
5 - -1 = 6
Step-by-step explanation:
8 hours 2 minutes. if you add 8hours to 10:13 you get 6:13 then just add 2 minutes and you will have 6:15 p.m
Answer:
![a=5m](https://tex.z-dn.net/?f=a%3D5m)
Step-by-step explanation:
![m=\frac{a}{5}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7Ba%7D%7B5%7D)
Swap sides:
![\frac{a}{5}=m](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B5%7D%3Dm)
Multiply both sides by 5:
![\frac{5a}{5}=5m](https://tex.z-dn.net/?f=%5Cfrac%7B5a%7D%7B5%7D%3D5m)
![a=5m](https://tex.z-dn.net/?f=a%3D5m)
Answer:
<em>y=-6</em>
Step-by-step explanation:
<em>Geometric Sequences</em>
Any given sequence is said to be geometric if each term
can be obtained as the previous term
by a constant value called the common ratio.
![a_n=a_{n-1}.r](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D.r)
or equivalently
![a_n=a_1.r^{n-1}](https://tex.z-dn.net/?f=a_n%3Da_1.r%5E%7Bn-1%7D)
Looking closely at the sequence 2, y, 18,-54, 162 we can try to find out if it's a geometric sequence or not. We compute the possible common ratios
and we see they both result -3. If we use r=-3 and try to find the second term (y), then
y=2*(-3)=-6
Now we compute the third term: (-6)(-3)=18
Since we got the third term as given in the original sequence.
So y=-6
