SOLVE: 4 - 2x = 10
x = ?

x= -3

Step-by-step explanation:

Step one: Simplify both sides

4-2x=10

4+ -2x=10

-2x+4=10

Step two: Subtract 4 from both sides

-2x+4-4=10-4

Step three: Divide both sides by -2

-2x/2 = 6/-2

x= -3

step-by-step explanation:

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%
