Answer:

$\boxed{x=\dfrac{121}{2}\to x=60.5}$

Step-by-step explanation:

$\dfrac{3}{6}=\dfrac{x}{121}\qquad\text{simplify}\ \dfrac{3}{6}=\dfrac{3:3}{6:3}=\dfrac{1}{2}\\\\\dfrac{1}{2}=\dfrac{x}{121}\qquad\text{cross multiply}\\\\2x=121\qquad\text{divide both sides by 2}\\\\x=\dfrac{121}{2}$

Answer:

60.5 =x

Step-by-step explanation:

3/6 = x/121

We can use cross products

3*121 = 6*x

363 = 6x

Divide by 6

363/6 = 6x/6

60.5 =x

Four integers are consecutive terms of an arithmetic sequence. The sum of these four numbers is 24 and the product is 945.Find t

Marta_Voda [28]

When common difference, $d=\sqrt{39}$ then the largest term of these four terms will be $6+3\sqrt{39}$

Let four consecutive terms of AP is,

$a-3d, a-d, a+d, a+3d$

Since, sum of all four terms is 24

So, $a-3d+a-d+a+d+a+3d=24\\\\a=6$

And product is 945

So, $(a-3d)(a+3d)(a-d)(a+d)=945\\\\9d^4-360d^2+351=0\\\\d^4-40d^2+39=0\\\\(d^2-1)(d^2-39)=0\\\\d=1,-1\\d=\sqrt{39}, -\sqrt{39}$

When d= 1, -1 then largest term is 9

When $d=\sqrt{39}, -\sqrt{39}$ then largest term is $6+3\sqrt{39}$
