Can someone help me? and answer step by step.

12.785

Step-by-step explanation:

you have to add the area of two rectangles and a quarter of a circle

the biggest rectangle size is 2 by 5, its area is then 2*5 = 10

the small one is 2 by 1, its area is 1*2 = 2

radius of the circle is 1, it's area is 1²π = 3.14 but you need only 1/4 of it so 3.14/4 = 0.785

total area is 10+2+0.785 = 12.785

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
