−7x−9+4.2+3x−5

Add −9 and 4.2 to get −4.8.

−7x−4.8+3x−5

Combine −7x and 3x to get −4x.

−4x−4.8−5

Subtract 5 from −4.8 to get −9.8.

−4x−9.8

Ps: I hope this is correct, hope it helps also have a great day.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
