1. -2x = 3x + 10
x = 5

-10 = 25

Step-by-step explanation:

-2x = 3x + 10

First, substitute in 5 for x

-2 x 5 = 3 x 5 + 10

Multiply -2 and 5 together

-10 = 3 x 5 + 10

Multiply 3 and 5 together

-10 = 15 + 10

Add 10 and 15 together

-10 = 25

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%
