I didn't guess. It would just take a long time to show all the work I did

240

Step-by-step explanation:

41

Step-by-step explanation:

-(-8) = 8 and

-(-14) = 14

so, 19 + 8 + 14 = 41

7/9

It simplifies to: -20x+14y-1

Step-by-step explanation:

This is really about combining like terms.

9-2x-18x+14y-10

1) Lets do the the x's first: -2x-18x = -20x

(It's -2 because of the minus sign)

2) Combine the 9-10 = -1

3) You can't combine +14y because theres no other y, so let's put the equation together: -20x+14y-1.

use a calculator But it is A

I'm pretty sure the second one bro
