Answer:

x = 36

Step-by-step explanation:

the 3 angles form a straight angle and sum to 180°

sum the 3 angles and equate to 180

3x + x + x = 180 , that is

5x = 180 ( divide both sides by 5 )

x = 36

Solve for x. −7.8(x+6.5)=−25.74

svetlana [45]

−7.8(x+6.5)=−25.74

-7.8x - 50.7 = -25.74

-7.8x = -25.74 + 50.7

-7.8x = 24.96

x = 24.96/-7.8

x = -3.2

so bruhhh the value of x is -3.2

A5=2500 and a8=312,500 in explicit form geometric Sequence and series

Goryan [66]

If $a_n$ is a geometric sequence, then there is some $r$ for which

$a_n=ra_{n-1}$

We have

$a_8=ra_7=r^2a_6=r^3a_5$

$312,500=2500r^3\implies r^3=125\implies r=5$

Then

$a_5=5a_4=5^2a_3=5^3a_2=5^4a_1\implies a_1=4$

So this sequence is recursively defined by

$\begin{cases}a_1=4\\a_n=5a_{n-1}&\text{for }n>1\end{cases}$

and explicitly by

$a_n=4\cdot5^{n-1}$
