Answer:

C.)0.5853267 ; D.)251.25169

Explanation:

3067/6730 + 9085/70097

0.4557206 + 0.1296061 = 0.5853267

205800/45097 + 98 -10 * 24 * 80050 - 100+1080 - 25x - 25x/254x

4.5634964 + 98 - 19212000 - 100 + 1080 - 25x - 25x/254x

4.5634964 + 98 - 19212000 - 100 + 1080 - 25x - 25x/254x

C.)

345x + (-100)= 987x (- 60/216 +88)

345x - 100 = 987x(87.722222)

345x - 100 = 86581.833

345x = 86581.833 + 100

345x = 86681.833

x = 86681.833 / 345

x = 251.25169
