You have 42 marbles in a bag. Inside the bag are 15 red marbles, 5 blue marbles, and the rest are whitd. If you reach into the bag and randomly select a marble, then what is the
probability the selected marble will be white?
Round to the 4th decimal place.

22

Step-by-step explanation:

there is 22 white marbles because 15 - 5 - 42=2.2

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
