coldgirl [10]

Rearrange unknown terms to the left side of the equation

$\boldsymbol{\sf{ 9x > 50.4-9 \ \ \longmapsto \ \ \ [Subtract]}}$

Calculate the sum or difference.

$\boldsymbol{\sf{9x > 41.4 }}$

Convert decimal to fraction.

$\boldsymbol{\sf{9x > \dfrac{414}{10} }}$

Reduce the greatest common factor for both sides of the inequality.

$\boldsymbol{\sf{x > \dfrac{46}{10} }}$

Reduce the fraction

$\red{ \boxed{\boldsymbol{\sf{\blue{ Answer \ \ \longmapsto \ \ x > \dfrac{23}{5} }}}}}$

Sunny_sXe [5.5K]

Answer:

Step-by-step explanation:

This arithmetic sequence starts at 1 and increases by 5 every time. The formula for this sequence could be expressed as A(n) = 1 + 5(n-1).

Since you're finding the 15th term, substitute n = 15 into the formula.

A(15) = 1 + 5((15)-1) = 1 + 5(14) = 1 + 70 = 71
