<u>Answer:</u>
a(n) = 130 + (n-1) 13
13th term = 286
<u>Step-by-step explanation:</u>
We are given a sequence of numbers: 130, 143, 156, 169, ... and we are to write an explicit formula to represent the arithmetic sequence and use it to find the 13th term.
We know that the arithmetic sequence can be defined by:
![a_n=d(n-1)+c](https://tex.z-dn.net/?f=a_n%3Dd%28n-1%29%2Bc)
where
= the common difference between consecutive terms ; and
=![a_1](https://tex.z-dn.net/?f=a_1)
<u>13th term:</u>
![a_{13}=130+(12)13 = 286](https://tex.z-dn.net/?f=a_%7B13%7D%3D130%2B%2812%2913%20%3D%20286)
Therefore, the formula for this sequence will be a(n) = 130 + (n-1) 13 and 13th term is 286.
The factor of 60x minus 84 using GCF is ![12(5x-7)](https://tex.z-dn.net/?f=12%285x-7%29)
Step-by-step explanation:
We need to factor 60x minus 84 using GCF
GCF stands for greatest common factor.
The greatest number that is divisible by both terms is known as GCF.
So we have the term ![60x-84](https://tex.z-dn.net/?f=60x-84)
The greatest common term is 12 which is divisible by both terms.
So, after taking common 12 we get:
![60x-84](https://tex.z-dn.net/?f=60x-84)
![=12(5x-7)](https://tex.z-dn.net/?f=%3D12%285x-7%29)
So, the factor of 60x minus 84 using GCF is ![12(5x-7)](https://tex.z-dn.net/?f=12%285x-7%29)

Answer:
180
Step-by-step explanation:
first you need to add ten to 80 and then it gives you 90, but tom had 100 and gave ten to Ahmad resulting in 10 more. so that means 90 x 2 = 180
Answer:
