(A) 360

Step-by-step explanation:

360*.40=144

360

Step-by-step explanation:

This can be done in more than one way, but i like the simpler way, so i will show you that. The simplest way to do this is to simplify the equation into a simpler way to do it. If you have 40%, that's hard to get to 100%, so divide it by 4. You will get 36, and that is now 10% of the unknown number. Then just multiply 36 by 10 and you get 360, which is your final number.

Hope this helped, please mark brainliest i need to feed my family ^_^

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

you probably already have the answer but anyways it's b. 15.0
