Solve 4(x−9)=4(9+13x).

The solution is x=

x = - = - 1.5

Step-by-step explanation:

Given

4(x - 9) = 4(9 + 13x) ← distribute parenthesis on both sides

4x - 36 = 36 + 52x ( subtract 52x from both sides )

- 4x - 36 = 36 ( add 36 to both sides )

- 4x = 72 ( divide both sides by - 4 )

x = = - = - 1.5

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%
