Solve. -3/5x + 1/5 > 7/20

1 answer:

5 0

-3/5x + 1/5 > 7/20

-3x + 1/5 > 7/20 join the denominators

-3x + 1 > 7/20 * 5 multiply both sides by 5

-3x + 1 > 35/20

-3x + 1 > 7/4

-3x > 7/4 - 1

-3x > 3/4

x < -3/4 ÷ 3

x < -1/4

hope that helps, God bless!

inessss [21]

Step-by-step explanation:

$a_1=6\\a_2=a_1+1\to a_2=6+1=7\\a_3=a_2+1\to a_3=7+1=8\\a_4=a_3+1\to a_4=8+1=9\\\vdots\\\\\text{The recursive formula}\\a_n=\left\{\begin{array}{ccc}a_1=6\\a_n=a_{n-1}+1\end{array}\right\\\\\text{It's an arithmetic sequence with}\ a_1=6\ \text{and difference}\ d=1\\\\\text{The explicit formula of an arithmetic sequence:}\\\\a_n=a_1+(n-1)d\\\\\text{Substitute:}\\\\a_n=6+(n-1)(1)\\a_n=6+n-1\\a_n=5+n\\\\a_n=n+5$
