Find a formula for the nth term of the arithmetic sequence.
First term 10
Common difference -3

For an nth term in an arithmetic sequence

U(n) = a + (n - 1 )d

a = first term

d = common difference

U(n) = 10 + (n -1)-3

= 10 - 3n + 3

= 13 - 3n

Hope this helps.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
