Preston placed 4 white marbles, 6 blue marbles, and 8 yellow marbles in a bag, if he
picks a marble without looking, what is the probability that the marble will NOT be blue?

Step-by-step explanation:

50% because 8+4=12

And 6 is half of 12 so he will have a 50% chance of getting a blue marble or not

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
