Step-by-step explanation:

ok, so just first, plug a and b into the equation to get:

.

Then do the squares in the denominator to get

then we change the fractions in the denominator to get a common denominator, to get: then we add the fractions to get: . 1409/100 = 14.09, and we simplify the number to .

10/14.09 ≈ 1, so that's your answer

Hope this helps! :D

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

answer: i guess 5 units?
