Answer:

4)x= g-c

5)x =u+k

6)x = g-c

7) $a=\frac{k}{u}$

8) $x= \frac{g}{c}$

9) $a=\frac{4}{12m}$

10) $x= \frac{2c+3}{3}$

11) $a=\frac{n+p}{m}$

12) $a= \frac{ub}{k}$

13)a= d -r + c

14) $x=\frac{np}{m}$

Step-by-step explanation:

4) g= c+x

x= g-c

5) u=x-k

x =u+k

6)g = c+x

x = g-c

7) $u=\frac{k}{a} \\\\a=\frac{k}{u}$

8) g=xc

$x= \frac{g}{c}$

9) 12am = 4

$a=\frac{4}{12m}$

10)-3x+2c = -3

2c = -3 +3x

2c +3 = 3x

$x= \frac{2c+3}{3}$

11) am= n+p

$a=\frac{n+p}{m}$

12) $u = \frac{ak}{b} \\\\u*b = ak\\\\a= \frac{ub}{k}$

13)a-c = d-r

a= d -r + c

14)xm= np

$x=\frac{np}{m}$

What is the 100th term if the sequence? 5 ,1 ,-3,-7

wel

5 ,1 ,-3,-7 ? what the dickens is going on?

notice, from 5 to 1, is really -4 units,

from 1 to -3, is -4 units as well, 1 -4 = -3 and so on.

so, to get the next term's value, you simply subtract 4 from the current one, namely -4 is the "common difference".

and we also know the first term is 5, ok... then

 $\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
d=-4\\
a_1=5\\
n=100
\end{cases}
\\\\\\
a_{100}=5+(100-1)(-4)\implies a_{100}=5+(99)(-4)
\\\\\\
a_{100}=5-396\implies a_{100}=-391$
